Lesson Learned: There's little more satisfying than watching the "cool" kids get their comeuppance.

Teen comedies, by definition, are prone to narrative immaturity. Thinking their target audience could care less about sharp intelligence and witty irreverence, screenwriters of nonsense such as She's All That settle for generic mediocrity, churning out a dumb script for pretty faces to lifelessly act out. And then there's a scribe like Tina Fey, who's smarter in her sleep than most of Hollywood's writers are on three cups of coffee.

Taking a crack at the high school movie genre, the hilarious and smart Saturday Night Live writer approached teenage classism with an inclusive spirit. The characters, from Lindsay Lohan's scheming good girl to Rachel McAdams' despicable another-word-for-female-dog, aren't caricatures—they're relatable even in their most heightened states, something Fey acutely knew would be crucial to selling the movie's higher caliber of lowbrow humor.

And, for the love of LiLo, don't call this one a “chick flick.” Excellent flicks, particularly hilarious ones, are gender neutral.
