The pioneering film portrait of a distinctive, universal, and heretofore ignored teenage social class: the bitter, frumpy, snobbish, willfully unpopular “weirdos,” self-defined only in their disdainful opposition to their peers. It’s a state that often provides for a certain amount of lostness after graduation, which is what the heroines of Daniel Clowes’s graphic novel and Terry Zwigoff’s acerbic movie struggle with: the vacuum left once they’re left to their own devices. Thora Birch and Scarlett Johansson are pitch perfect in what amounts to an act of modern anthropology—the rescuing of a lovable misfit-teen type from obscurity. With Steve Buscemi.
