John Tucker Must Die is a 2006 comedy film starring Brittany Snow and Jesse Metcalf. It was directed by Betty Thomas.A cheerleader, Heather, a vegan human rights activist, Beth, and the student body president type, Carrie, team up to bring down the guy that dated them all at once and then broke their hearts. Kate, a new girl at the school, has never dated a John Tucker but gives the trio advice based on her mother's love life. Together they hatch a plan to break John's heart the same way he broke theirs, using inexperienced Kate as the fake dater.As the girls are molding Kate into everything she needs to be to win John, she's caught the eye of the "other Tucker," John's little brother. The first couple of schemes, from giving John estrogen pills to make him more emotionally sensitive and implying he has herpes through sex ed ads, do not work to ruin his reputation as a ladies man. As he gets closer to Kate he starts to fall hard and that's when she decides she bit off more than she can chew. When John's birthday rolls around everything comes out into the open and Kate has to stop pretending to be something she's not.
Alpha Bitch: Heather, a bit downplayed, but for sure she has some traits. Also Kate, but she gets better. However, Beth and Carrie are nearly as bad, in spite of occupying roles that would normally be more sympathetic.
Anti-Hero: Kate is the film's protagonist, but her goal is to humiliate John by manipulating his emotions.
Even accounting for their (pretty legitimate) Woman Scorned feelings Beth, Carrie and Heather come across as rather unlikable. Heather is the worst, smugly throwing a luckless cheerleader off her team to further the plan, but even the other two come across as patronising and insensitive towards Kate.
Did Not Get the Girl: Kate changes her mind about humiliating John, but the other girls play the pre-recorded "I'm Dumping You" video anyway. Defying genre convention, he doesn't take Kate back afterward.
Good Adultery, Bad Adultery: John Tucker's actions are a clear example of bad adultery given the highly elaborate efforts he made to keep his girlfriends from finding out about each other, and it's likely the entire revenge plot could have been avoided had he simply told them they weren't dating exclusively. At the end he's shown introducing his new girlfriends to each other and making it clear he's going to date them concurrently, showing he learned his lesson.
Good Parents: Kate's single mother is a good mother towards her, offering her advice for everything.
Karma Houdini: Everyone. Seriously. All the girls get away with torturing John all year, and John gets away with being the school slut all year all with one little apology. Then they all forgive each other and have a wacky food fight.
