Universal

Everyone loves a bad boy. The snarling mustache twirlers get all of the fame and fortune -- the No. 1 spot on movie-geek lists, the Halloween costumes, the cool quotes -- and none of them have to worry about being called a witch.

But here at NextMovie, we're all about the bad girls. We love a lady who isn't afraid to embrace her nasty side in order to get what she wants.

In honor of "Savages" and Salma Hayek's role as a brutal drug cartel leader, we've gathered up the coolest and cruelest women to grace the silver screen. We're a little worried about ranking them, because if there's one thing we know about these vicious villainesses, it's that they don't like competition. But we did. Now, you read. We'll run.

15. Rebecca Romijn as Mystique in the 'X-Men' Movies (2000-06)

20th Century Fox

Mystique's level of menace shifts with every new "X-Men" installment. She can be a silent and unstoppable foe who nearly levels Wolverine (no mean feat), or she can be the weary warrior who is just tired of mutants being persecuted. It's hard not to root for her as she slinks into Senator Kelly's skin, and awfully difficult to like her when she's trying to wipe out all of humanity. At the same time, we want to be her, because blue skin seems like a good trade-off for the ability to become anyone we want.

14. Salma Hayek as Satanico Pandemonium in 'From Dusk Till Dawn' (1996)

Dimension Films

Sexy vampires may be all the rage these days, but we can't think of a single fanged female who compares to Satanico Pandemonium. Her luscious striptease is powerful enough to silence an entire bar of truckers and bikers ... which makes scooping them up and draining their blood a heck of a lot easier. We're not quite sure why she's slumming it in a Mexican dive with that kind of power, but maybe she likes the weather.

13. Rachel McAdams as Regina George in 'Mean Girls' (2004)

Paramount

When you're a teenager, no villain looms larger than the Popular Pretty Girl, and Rachel McAdams' Regina seems to have taken bits and pieces from every one that ever existed in the history of high school. She's simultaneously shallow and brilliant, able to ruin lives with a single phone call or well-flung sentence. Just watching her smirk and flick her hair is enough to make us queasy enough to call in sick ... and we're not even in high school.

12. Faye Dunaway as Joan Crawford in 'Mommie Dearest' (1981)

Paramount

If you ever wondered how all the ladies on this list went so wrong, you probably have to look into the deep past, where they undoubtedly had a mother like Joan Crawford. Crawford terrorizes everyone in the film -- her boyfriend, her studio, her personal assistant, her maid. But it's her children that receive the worst of it. Her loathing of wire hangers has gone down into infamy, but the birthday party scene (in which daughter Christina watches all her presents go to charity) is enough to turn a girl into an evil queen or a desperate stalker.

11. Michelle Pfeiffer as Catwoman in 'Batman Returns' (1992)

Warner Bros.

If Batman had to lose to anyone in his rogues gallery, it ought to be Pfeiffer's Catwoman. Her costume is fantastic, her motivation is actually pretty noble, her weapons are elegant (claws and a whip! They make the bat-tools look clunky) and her sarcastic "Meow" implies she knows exactly how ridiculous dressing up like an animal is. Plus, she has nine lives and a pack of furry allies. Last we checked, Batman only had one, and a butler to keep him company. Advantage: Catwoman.

10. Louise Fletcher as Nurse Mildred Ratched in 'One Flew Over the Cuckoo’s Nest' (1975)

United Artists

Nurse Ratched doesn't seem so bad when you first meet her. She's just a nurse, and one working in a difficult and dangerous place, at that. But then you get to know her, and you realize that beneath the starch and soft voice is a woman who thrives on controlling, humiliating and drugging her patients into compliance. She meets her match in Randle McMurphy (Jack Nicholson), but Ratched quietly and ruthlessly ups the ante. The result is heartbreaking, and barbaric enough to make just about everyone else on this list shudder.

9. Lucy Liu, Daryl Hannah, and Vivica A. Fox as the Deadly Viper Assassination Squad in 'Kill Bill: Vol. 1' (2003), and 'Kill Bill: Vol. 2' (2004)

Miramax

No one can write a killer quite like Quentin Tarantino, and his DIVAS are no exception. They're beautiful, deadly and just a little bit insane. Lucy Liu's O-Ren Ishii will lop heads off Tokyo rivals just for an insult, Elle Driver will poison you without blinking and Vernita Green will challenge you to a knife fight before shooting you in the back. Combined, they will happily beat and shoot a former colleague into a coma. There are no giggly girlfriends here, just bloodthirsty ambition, and there's not a soul who envies the Bride in taking them on.

8. Sharon Stone as Catherine Tramell in 'Basic Instinct' (1992)

TriStar

A good villain hides her tracks. A great villain doesn't bother, and Stone's Catherine Tramell doesn't hide a darn thing. Literally. Cinema is full of femme fatales, but Stone redefined the term when she slipped on that white dress and lit up a cigarette to have a very friendly chat with the police. Her bare-it-all tactic works. Despite her fingerprints being on practically every murder weapon (particularly the movie's iconic icepick), the men keep lining up to hop into bed with her, and she remains in the clear.

7. Anne Ramsey as Mama Fratelli in 'The Goonies' (1985)

Warner Bros.

Not all villainesses are born as elegant screen goddesses. Some are like Mama Fratelli -- square bulldog types who don't mess around with stilettos and sheath dresses, but dress practically in case there's a shoot-out with the cops. (She wears pearls, though. A mob dame can still accessorize.) She's handy with a pistol, hard with her fist, steely behind the wheel and not about to let a bunch of brats take away her pirate treasure. Something tells us she could slap sense into the other villainesses on this list, set them straight, and keep the spoils for herself.

6. Glenn Close as Alex Forrest in 'Fatal Attraction' (1987)

Paramount

"I won't be ignored, Dan." With those five words, said with just the right amount of sinister wobble, men all over the world gulped and promised to be a little more wary of a woman who seemed too good to be true. And oh, Alex is incredible. She's fun, brilliant, sexy, carefree and eager for a weekend fling. But when she doesn't want to give her new man up, the knives come out, and not even the beloved family pet is safe.

5. Meryl Streep as Miranda Priestly in 'The Devil Wears Prada' (2006)

20th Century Fox

We've all had bad bosses in our lives. But none of them have made a cell phone ringing sound as blood-curdling as Miranda Priestly does. If you work for her, you are expected to stop hurricanes, get the next Harry Potter book before it is published, be an invisible delivery girl and remember the names of hundreds of partygoers. You will also be humiliated daily and risk never working in publishing again. All the Christian Dior in the world couldn't be worth it.

4. The Evil Queen in 'Snow White and the Seven Dwarves' (1937)

Disney

Evil queens and witches dot the Disney landscape, but they all owe a debt to the Evil Queen, who was the first to menace a chirping and delicate Disney princess. She initially does it with style (that dress! those eyebrows!) before traumatizing many a young child by turning into a haggard, bug-eyed crone. Plus, she's the only one on our list who has her own dungeon. You have to admire the steel of a woman who just leaves guys chained up in the basement until they're bones.

3. Kathy Bates as Annie Wilkes in 'Misery' (1990)

Columbia Pictures

If you're a badly injured writer out in the middle of snowbound nowhere, Annie initially seems like a godsend -- she's a trained nurse, unassuming and enthusiastic. Instead, she's exactly what people think of when they hear the words "dedicated fan," and that's someone who would hobble a handsome actor or talented musician before she'd let him go. And really, haven't we all been there?

2. Margaret Hamilton as The Wicked Witch of the West in 'The Wizard of Oz' (1939)

MGM

This green-skinned cackler has been given a bit of a revisionist makeover in recent years, but let's not forget how we originally met her: threatening Dorothy and her little dog, too. Every scene she's in is terrifying -- rallying her flying monkeys, writing black smoke messages in the sky and taunting Dorothy (by way of Auntie Em) through her glass ball. Never has a bucket of water been such a relief to so many.

1. Helena Bonham Carter as Bellatrix Lestrange in the 'Harry Potter' Movies (2007-11)

Warner Bros.

Actresses normally shy away from playing big bads. But not Helena Bonham Carter, who will happily take play murderesses and madwomen. While the diabolical Mrs. Lovett of "Sweeney Todd" requires a tip of the meat cleaver, it's the demented Bellatrix Lestrange who has conjured her way onto this list. She has no qualms about dishing out killing curses, torturing students, breaking into the Ministry of Magic, and stabbing house elves for her beloved Voldemort. Her list of crimes is long, her cackle is terrifying, and the only thing crazier than her eyes is her hair. It's supremely fitting that she's taken down by the epitome of homely kindness in Mrs. Weasley. Wherever Bellatrix is, she's probably still seething over that injustice.

Summit

Be it for money, bargaining purposes, or strictly out of necessity, movie characters have been getting kidnapped since silent-era evildoers began the mini industry of tying women to train tracks.

Not all kidnappers are mustache-twirling villains, though. In fact, many of them have a darn good reason and are pretty nice folks once you're forced at gunpoint to get to know them. Amanda Seyfried could sure use some do's and dont's in the new kidnap thriller "Gone," but if you ever do get kidnapped in a film, we have a few rules to live by so you don't wind up on a milk carton … or in a wood chipper.

Follow the Kidnapper's Instructions

Evidence: "Fargo," "Ransom," "Misery," "Alpha Dog," "Silence of the Lambs"
As a result of William H. Macy's greed in scheming an inside-kidnapping job with a skeevy Steve Buscemi in "Fargo," about a dozen people lost their lives. That's not so Minnesota nice, don't ya know. Mel Gibson rolled the dice on turning the tables on his son's kidnappers ("Ransom"), but he only got away with it because he's bats**t crazy. James Caan might not have gotten his ankles hammered by Kathy Bates in "Misery" if he'd just played along with her deranged demands, but Justin Timberlake actually told Anton Yelchin to go home at one point before he was later forced to gun the stupid kid down ("Alpha Dog"). If we've learned anything, it would be that whatever you do, for God's sake put the lotion in the basket ("Silence of the Lambs").

20th Century Fox

Be an Adorable Hostage

Evidence: "The Nightmare Before Christmas," "Labyrinth," "Raising Arizona," "A Perfect World," "Rain Man"
"Kidnap the Sandy Claws …" It's a cute tune revolving around a capital crime, made all the cuter by the rosy-cheeked plasticine puppet Tim Burton concocted for Father Christmas in "Nightmare Before Christmas." David Bowie amused his baby kidnapee by creepily fondling little crystal balls ("Labyrinth"), while Holly Hunter and Nicolas Cage did their best to domesticate Nathan Jr. to their humble trailer park abode ("Raising Arizona"). Kevin Costner seemed to be forming a pretty decent father-son bond with his captive kid before getting shot in a field ("A Perfect World"), but Dustin Hoffman's idiot savant in "Rain Man" got some refreshing brotherly love from Tom Cruise … after he was used as a human calculator to win big in Las Vegas.

Don't Fall in Love With Your Abductor

Evidence: "12 Monkeys," "3 Days of the Condor," "V For Vendetta," "Out of Sight"
Stockholm Syndrome can be a tricky thing, especially if you're a time traveler falling for your shrink while you keep foreseeing your own death like poor Bruce Willis ("12 Monkeys"). A bookish Robert Redford became a Casanova to Faye Dunaway in "3 Days of the Condor") once she knew he was a spy playing for keeps. Natalie Portman had to have her head shaved in an elaborate brainwash before she fell for V, her mutilated masked abductor; but all it took for George Clooney and J.Lo to start knocking boots in "Out of Sight" was a cozy ride in a car trunk.

Realize Escape May Be Impossible

Evidence: "Air Force One," "Panic Room," "9 to 5"
Whether you're President Harrison Ford in a fuselage miles in the sky ("Air Force One"), Jodie Foster and Kristen Stewart trapped in an impenetrable room ("Panic Room"), or a rascally Dabney Coleman chained up like some S&M gimp ("9 to 5"), trying to get yourself free can be one futile enterprise. Usually the fight or flight instinct kicks in, or both in the case of "Air Force One."

20th Century Fox

Make Sure a Loved One Has Combat Training

Evidence: "Taken," "Commando," "Man on Fire," "Rambo"
Liam Neeson cornered the market on middle-aged badassery when he used his special set of skills to hunt down and take out the dudes who took his daughter in "Taken." Ditto for Special Forces-trained Arnold Schwarzenegger in "Commando," who pretty much enacted the same scenario in the finale of "True Lies." Denzel Washington in "Man on Fire" was a disgraced former CIA agent who gave it all up for our generation's Shirley Temple, i.e. Dakota Fanning. And John Rambo didn't even know the missionaries he rescued by slaughtering what-seemed-like-hundreds of Burmese military dudes, but whatevs.

Don't Waste Your Whole Life

Evidence: "The Searchers," "Oldboy"
This one applies to both kidnappers and the poor saps trying to rescue those taken. In "The Searchers," John Wayne and Jeffrey Hunter made tracking down little Debbie a full-time job that took longer than Boston's Big Dig, so much so that when they finally found her she had blossomed into Natalie Wood in Native American garb. Then in "Oldboy" you have the sick, twisted **** that is Lee Woo-jin, who kept Oh Dae-su captive for 15 frickin' years before letting him go in one of the most wildy circuitous (and perverted) revenge schemes in history. Next time just take a chill pill and get on with your lives already, people.

Don't Be Mary Jane Watson

Evidence: All-three "Spider-Man" movies
This is a pretty self-explanatory rule that shouldn't concern most of you, but in that rare instance that you happen to be the object of Peter Parker's affection, we recommend keeping to a safe house or far-off island. All this parading out in public as a fashion model or Broadway singer or whatever it is you do -- this has gotta stop. We hate to blame the victim, but when you get nabbed by Green Goblin, Doc Ock AND Sandman, it's time to re-evaluate your web-slinger fetish.

Sony Pictures

Does the new Minka Kelly/Leighton Meester thriller "The Roommate" look like "Fatal Attraction" for the college set?

Yes, and there's nothing wrong with that. In fact, "The Roommate," in which "Gossip Girl" star Meester plays a college student who becomes obsessed with her roommie (Kelly), promises to be another fine entry in the sub-genre of psychological thrillers we actually think of as the "PWF" flick: Psycho White Females.

You know 'em: those crazy movie villainesses who wreak havoc on the men, women and children (and sometimes poor, innocent bunnies) around them, usually on the heels of some brief or imagined love relationship.

In honor of "The Roommate," we're counting down our nine favorite PWFs who've come before them.

9. Erika Christensen, 'Swimfan' (2002)

Fox

"Fatal Attraction" for high schoolers? Check, as Christensen's Madison is a girl who knows what, or rather who, she wants, and will go to any lengths to get him. And if she can't get her man, well, she'll get her man. In this case, it's aspiring swim champ Ben (Jesse Bradford), who cheats on his girlfriend Amy (Shiri Appleby) via a sexy pool romp with Madison. He's immediately remorseful about his infidelity, but not as sorry as he is when the scorned Madison wrecks his car, sets him up to fail a drug test, kills his BFF and frames Ben for it and tries to kill Amy. Yikes.

8. Rebecca De Mornay, 'The Hand That Rocks the Cradle' (1992)

De Mornay's Peyton had been through a tragedy: Her obstetrician husband committed suicide after one of his patients, Claire (Annabella Sciorra), reported him for molesting her during an exam. Peyton lost her hubby, her house, her financial security and, thanks to the stress of the situation, her own pregnancy.

Her rebound plan: to destroy the pregnant Claire and her family, by changing her identity, getting hired as Claire's nanny and slowly turning her fam and friends against her. It doesn't work, of course, but along the way, Peyton does manage to terrorize an elementary school child, frame the family's developmentally disabled handyman (Ernie Hudson) as a pedophile and murder Claire's best friend (Julianne Moore) in a gruesome shattered greenhouse trap that would make "Saw'"s Jigsaw proud.

7. Drew Barrymore, 'Poison Ivy' (1992)

The movie that marked the beginning of Drew Barrymore's comeback also found her playing a very bad bad girl. Trashy teen Ivy (Barrymore) has a miserable family life, but she feels right at home with pal Sylvie (Sara Gilbert), Sylvie's uptight dad Darrel (Tom Skerritt) and Sylvie's sick mother Georgie (Cheryl Ladd). The life that angsty Sylvie rebelled against, in fact, was Ivy's ideal, so she proceeds to seduce Darrel (in an over-the-top, sex on the car hood scene in a rainy forest) and push Georgie off a balcony and make it look like suicide.

6. Jennifer Jason Leigh, 'Single White Female' (1992)

Sony

In yet another entry that proves 1992 was a good year to be a PWF on the big screen, Leigh plays Hedy, a shy, lonely woman who seems like the ideal roommate for It Girl Allie (Bridget Fonda), whose heart had just been broken by her cheating boyfriend Sam (Steven Webber). Allie and Hedy forge a sisterly bond, until clingy Hedy wants not just to be like Allie -- right down to copying her hair cut and color and buying the exact same clothes -- but to actually be Allie.

When Hedy's disturbing past is revealed (there was a dead twin involved), she tries to kill Allie and Allie's gay BFF Graham (Peter Friedman), pretends to be Allie while having sex with Sam and then kills him by plunging a stiletto heel into his head. And she wonders why she's still single.

5. Sharon Stone, 'Basic Instinct' (1992)

1992 again! Stone's Catherine Tramell is a bit less overtly psycho than the other PWFs on our list, but she is every bit as violent. The film's opening moments show the sex-and-murder scene that leaves Catherine as the main suspect for San Francisco detective Nick (Michael Douglas) and his partner Gus (George Dzundza). Nick is helplessly attracted to writer Catherine, and a game of cat-and-mouse leaves him guessing about everything about Catherine -- except whether or not she wears underwear, that much is transparent thanks to the infamous leg-crossing scene.

4. Ali Larter, 'Obsessed' (2009)

Sony

In a slight twist on the usual PWF/"Fatal Attraction" plot, handsome businessman Derek (Idris Alba) doesn't actually cheat on his wife Sharon (Beyoncé Knowles) with flirty temp Lisa (Larter). But that doesn't squash Lisa's obsession with Derek; it only fuels it, which ultimately leads to a misunderstanding that paints Derek as a philanderer to his wife, his co-workers and a pesky cop after Lisa fakes a suicide attempt. And even after the truth came out, Lisa still breaks into Derek and Sharon's house, briefly kidnapping their son and destroying their bedroom, leading to a final showdown between the two fierce women. You'll never guess who wins.

3. Kathy Bates, 'Misery' (1990)

The word "fan" is a derivation of the word "fanatic," and it has never been more literally applicable than in this fantastic adaptation of Stephen King's short story about the brief relationship between a novelist and his biggest fan. Bates won both an Oscar for her scary, and campy, performance as Annie Wilkes, a woman who rescues and nurses back to health novelist Paul Sheldon (James Caan) when his car goes off the road during a blizzard while he's visiting Colorado.

Paul has two broken legs, and is cautious, but grateful when he awakens in Annie's house. He's delighted she's a fan of his "Misery" novels, but when he doesn't return her affections, and when she finds out he planned to kill off the heroine of her beloved "Misery" novels, the denim dress-wearin' Annie wigs out, re-break Paul's legs (in the infamous sledgehammer scene), forces him to rewrite the book and then plots their joint demise.  

2. Helena Bonham Carter, 'Harry Potter' Series (2007-2010)

Not your "typical" PWF, sure, but Female Death Eater, aunt to the nasty Draco Malfoy and one of the most loyal cohorts of He Who Must Not Be Named... you know there's going to be some evildoing afoot when all that is part of Bellatrix Lestrange's bio. In "Order of the Phoenix," the first "Potter" movie in which Bellatrix is a major player, she menaces on Voldemort's behalf, and breaks Harry Potter's (Daniel Radcliffe) heart when she kills his godfather (and her own cousin!) Sirius Black (Gary Oldman). She does not get any more sane over the next three installments.

1. Glenn Close, 'Fatal Attraction' (1987)

Paramount

It's the grandmommy of all PWF flicks, not just because Oscar nominee Glenn Close's Alex tries to kill herself after sleeping with married man Dan (Michael Douglas) or because she pours acid on his car when he later rejects her or because she shows up at his apartment and plays nice with his wife Beth (Anne Archer), all the while pretending not to know Dan. Oh, or because she kidnaps his daughter Ellen from school.

No, she might have gotten away with all that, but the number one rule in movieland is that you can't kill an animal and get away with it, so when Alex breaks into Dan's house, takes Ellen's beloved pet bunny from its hutch and leaves it boiling in a pot on the stove, you know her well-deserved death is imminent.

Fox Searchlight

With critics figuratively swooning and audiences literally fainting, Danny Boyle's disarming new film "127 Hours" has become the "Dare I see it?" movie of the season.

The inspirational tale chronicles the real-life ordeal of hiker Aron Ralston (James Franco), who became trapped under a boulder and cut off his own arm to escape. The graphic depiction has left the squeamish running for the exits and us reminiscing about scenes we love to watch through our fingers.

Here are our top nine. (Warning: May cause flashbacks and/or nausea.)

9. Shot to the Heart – 'Pulp Fiction' (1994)

Miramax

Anticipation is like a petri dish for fear: the longer an audience is made to wait for a fright, the more aggressively their fears germinate. And no one cultivates anticipation like Quentin Tarantino. Vincent (John Travolta) knows that to save an overdosing Mia (Uma Thurman), he must jab a wickedly large syringe full of adrenaline though her breast plate and into her heart. But, gross. Who wants to do that? As Vincent procrastinates said chest puncturing, audiences' imaginations ran wild with the gory possibilities.
Watch the scene

8. Genital Hospital – 'Antichrist' (2009)

Let's talk now about bad life choices. When a therapist (Willem Dafoe) decides to treat his own wife (Charlotte Gainsbourg) for depression (bad choice) after the loss of their child, one could safely say she doesn't respond well to his methods. After smashing his man parts with a block of wood (really bad choice), she takes a pair of scissors to herself and does... a horrible thing (worst choice ever). Don't make us say it. Can we all just agree that this one deserves to be on the list and move on?

7. The George Clooney Manicure – 'Syriana' (2005)

Warner Bros.

If you'd like to watch a movie that will deter you from joining the CIA, this is it! George Clooney plays an undercover agent who has the misfortune of being tortured by terrorists. And it's not THAT bad. But then they tape his hands to a board and yank out his fingernails with pliers; continuing to watch the screen seems incompatible with continuing to hold on to one's lunch.
Watch the scene

6. Two Guys, One Fire Extinguisher – 'Irreversible' (2002)

Most films devoted to crushing our souls complete the task during their climax. But since "Irreversible" is told backwards, one needn't wait to be traumatized. Within the first minutes, a man avenges the rape of his girlfriend by repeatedly smashing the face of her suspected assailant with a fire extinguisher. While excruciating to watch, it does answer the age old question: What does it look like when someone's face gets repeatedly smashed with a fire extinguisher? Answer: It looks like the worst thing you've ever seen.
Watch the scene

5. Sloth – 'Se7en' (1995)

In "Se7en"'s menagerie of gruesome corpses, the victim representing Sloth is most cringe-inducing. The pedophile's been tied to a bed for a year, kept alive by IV drip as his body decays in its own filth. As Brad Pitt and Morgan Freeman examine the scene, finding photos of the man taken over his year of confinement, the ramifications of this zany prank chill one's flesh. And then the corpse starts coughing...
Watch the scene

4. Lend Me Your Ear – 'Reservoir Dogs' (1992)

Miramax

Stealers Wheel's hit "Stuck in the Middle" blares on the radio as Mr. Blonde (Michael Madsen) dances around his duct-taped hostage cop with a straight razor (duct tape: the psychopath's best friend). And neither we, nor "Stuck in the Middle" have been the same since. For no apparent reason, Blonde cuts off the cop's ear and plays with it while audiences everywhere got lightheaded in a different manner of speaking.
Watch the scene

3. You Are What You Eat – 'Hannibal' (2001)

Forced to sit at a dinner table, Agent Starling (Julianne Moore) watches in horror as her host, Hannibal Lector (Anthony Hopkins) lifts off the top of her co-worker's (Ray Liotta) skull, revealing his exposed brain. Lector cuts off morsels of grey matter, cooks them, and feeds them back to Liotta, who is too drugged up to realize what's happening or how truly bad this meal is for his health.
Watch the scene

2. Writer's Block – 'Misery' (1990)

MGM

This is not the fan club novelist Paul Sheldon (James Caan) envisioned. Taken hostage by Annie (Kathy Bates), his most devoted reader, Paul is forced to write a new book just for her. Not one to work on spec, he attempts escape but is caught and hobbled; a procedure wherein Annie straps Paul to his bed, places a wooden block between his ankles, and whacks the sides of his feet with a sledgehammer, breaking his foot bones over the block. Everybody's a critic.
Watch the scene

1. Curb Side Pick Up – 'American History X' (1998)

It's easy to overlook the evocative power of sound. When skinhead Derek (Ed Norton) forces a man to lie down on the street and wrap his mouth around the sidewalk curb, it's apparent no happy memories are in the works. As the scraping of teeth against concrete prickles your eardrums, your own teeth can't help but become nervous. When Derek kicks the back of the man's neck in, there's no person watching who won't seize-up from the horrifying sound.
