The cutting wit of Tina Fey (the first female head writer for Saturday Night Live) brilliantly fuses pop culture and smart satire. Fey wrote Mean Girls, in which a formerly home-schooled girl named Cady (Lindsay Lohan, Freaky Friday) gets dropped into the sneaky, vicious world of the Plastics, three adolescent glamor-girls who dominate their public high school's social heirarchy. Cady first befriends a couple of art-punk outsiders who persuade her to infiltrate the Plastics and destroy them from within--but power corrupts, and Cady soon finds the glory of being a Plastic to be seductive. Mean Girls joins the ranks of Clueless, Bring It On, and Heathers, cunning movies that use the hormone-pressurized high school milieu to put the dark impulses of human nature--ambition, envy, lust, revenge--under a comic microscope. Fey manages to skewer everyone without forgetting the characters' hapless humanity; it's a dazzling and delightful balancing act. --Bret Fetzer
