Gummo
Gummo (1997) is the directing debut of Harmony Korine. It follows the lives of several poor, white-trash people in Xenia, Ohio, a town that years before was struck by a tornado. The movie lacks any kind of storyline or plot, and consists of loose vignettes in which we see the town's inhibitants pass the time in original, somtimes disturbing ways. It is often considered a cult classic.
