15. Cooley High (1975)
Director: Michael Schultz
Stars: Glynn Turman, Lawrence Hilton-Jacobs, Garrett Morris
The movie that gave us What's Happening! (nice "adaptation," TV execs) looked at the lives of black inner-city high school kids without getting bogged down in slapstick or melodrama. Definitely one of of those funny-because-it's-true deals, and has given us plenty of pop culture touchstones because of it (to wit: the movie theater scene that the Fugees jacked for their "Killing Me Softly" video).
