Jennifer (Megan Fox)
The Girl: Jennifer hasn't always been a bad girl. And it's not her fault. It's that pesky demon that's taken over her body.
The Badness: Jennifer is a man-eater. Literally.
Unable to digest normal food, she realises that the only thing that will satiate her diabolic appetite is human-flesh.
We're not sure we'd mind all that much if Megan Fox's face was the last we ever saw.
So Bad She’s Good? Oh boy, yes. You'll want to leave the door wide open and cover yourself in ketchup.
Maxine Lund (Catherine Keener)
The Girl: Maxine is the office bitch.
She's such a good character because everyone knows a Maxine - she's the one everybody adores. It doesn't seem to matter that she's a despicable human.
The Badness: Maxine manipulates people into falling in love with her. Then she uses them. For money!
She's our kinda woman.
So Bad She’s Good? Not really. Before long, all that 'me me me' would really get on your wick.
Madeline LeClerc (Kate Winslet)
The Girl: Maddy is a humble laundry wench at Charenton, an insane asylum.
It's home to the Marquis de Sade, who's in trouble for writing rude things.
The Badness: Naughty Maddy smuggles the pornographic manuscripts out of the asylum and away to the publisher.
It doesn't sound that bad, though when you consider that this is nineteenth century France, and Napoleon wants the Marquis' head on a plate, it's quite a big deal.
So Bad She’s Good? Absolutely. And if not, her boobies look amazing, so it's impossible not to be tempted.
Mallory Knox (Juliette Lewis)
The Girl: Psychologically maimed by an abusive past, Mallory becomes the demonic bride of Woody Harrelson's Mickey.
The two embark upon a killing spree across America.
The Badness: Well, there's all them murders for starters.
She even killed her own parents. Come on. Everyone hates their parents when they're growing up, right? Killing's a bit OTT.
So Bad She’s Good? We're afraid Mallory might be beyond redemption. She's too bad to be tempting.
Jewel Valentine (Liv Tyler)
The Girl: Jewel wields an awesome power over men. Her allure is so intoxicating that she has everyone eating out of the palm of her beautiful hand.
The Badness: After shooting a man dead, Jewel shacks up with Randy (Matt Dillon).
Pretty soon, she's making some rather greedy demands, forcing Randy into a life of crime.
She's very persuasive.
So Bad She’s Good? She is very, very bad. And yes, it is good -bad. If you need convincing, just watch the car-wash scene.
Bellatrix Lestrange (Helena Bonham Carter)
The Girl: She's the loose cannon whose favourite past-time involves murdering Harry Potter's loved ones.
The Badness: Compared to Bellatrix, Bonham Carter's sociopathic Marla ( Fight Club ) and sinister Mrs. Lovett ( Sweeny Todd ) are as meek as kittens.
Bellatrix is truly, truly evil. The kind of evil you only find in kids' movies. But scarier.
So Bad She’s Good? Hell, no. We'd keep a wide berth. This one ain't messing around.
O-Ren Ishii (Lucy Liu)
The Girl: Head of the Tokyo yakuza and former member of the Deadly Viper Assassination Squad, O-Ren Ishii (codename "Cottonmouth") is one of The Bride's sworn enemies.
The Badness: Let's see. She's leader of a powerful criminal organisation and she used to murder people for money.
Plus, she was involved in the attempted murder of The Bride and her unborn child.
We're not sure if there's a badge for that in the Girl Guides.
So Bad She’s Good? She's beautiful, sure - but she's mighty intimidating. Perhaps a little too bad.
Lisa Rowe (Angelina Jolie)
The Girl: When Susanna (Winona Ryder) arrives at a mental institution, she thinks she's got problems.
A few minutes in the company of Lisa Rowe is enough to make those problems shrink into mere trifles.
The Badness: Sociopathic Lisa refuses to take her medication. She's lived at the hospital for seven years, though she keeps trying to escape.
Lisa spends much of her time bullying other residents - with disastrous consequences.
So Bad She’s Good? In a weird way, yes. Though she is barking mad, there's something seductive about her wild eyes and viscious ravings.
Alice (Natalie Portman)
The Girl: Alice arrives in Britain, fresh from the US, bright-eyed and bushy-tailed. She immediately falls in love with Dan (Jude Law) and they embark upon a rather stormy relationship.
The Badness: Well, she's a stripper. She takes off her clothes and wriggles her bottom at men.
Which isn't criminal ly -bad, but it's hardly your average shop-job, is it.
So Bad She’s Good? We didn't think it was possible to make Natalie Portman any more attractive. Who'd have thought that some spangly underwear and a pink wig would do it?
Kathryn Merteuil (Sarah Michelle Prinze/Gellar)
The Girl: Super-popular and extremely wealthy, Kathryn has no qualms with exploiting her sexuality to get what she wants.
Apparently that makes her a bad girl, though we would argue that she's just resourceful.
The Badness: In a bet to win her step-brother's Jag, she thinks nothing of utterly destroying a good few peoples' lives.
She also keeps cocaine in a hollow crucifix around her neck. Sneaky devil.
So Bad She’s Good? She's white-hot and totally tempting. Bad, bad girl.
