John Singleton’s third feature (1995)a decisive improvement on Poetic Justice but less fully realized than Boyz N the Hoodoffers a street-smart view of multiracial campus life at a fictitious middle-American university. Among his perceptions is that American education currently functions like a business. The characters include three freshmena black athlete on a track scholarship (powerfully played by Omar Epps), a white woman (Kristy Swanson) coping with a near rape and flirting with bisexuality, and a highly disaffected white youth (Michael Rapaport) who joins a gang of neo-Nazi skinheads. There’s also a stern but understanding professor (Laurence Fishburne), and Ice Cube has a nice part as a malingering intellectual. Aiming at a microcosm of American life comparable in some ways to Do the Right Thing, Singleton can’t quite justify or explicate his parting message (unlearn), but his passion is exemplary.
