Jennifer's Body was impressive enough (when I saw it on a whim years after it came out) that I looked up its writer (Diablo Cody) and what else she'd done. Which led me to Young Adult. Wow! And: Ooof! Powerful stuff.
Or as one critic put it: "Young Adult may be the year's most engaging feel-bad movie".
Is there an effedupmovies site? All I can find are lists on other sites (Letterboxd, IMDB, Ranker etc).
