In this kaleidoscopic grungefest, a group of pretty young crystal-meth junkies bounce off one another like pinballs. The director, Jonas Akerlund, uses stroboscopic cuts, shock sound, and triple-X animated imagery to put us inside the experience of a crank high. Akerlund has an instinct for dirtbag theatrics. Spun is accomplished, but it's also numbing. The cast, slumming for cred, includes Jason Schwartzman, Mena Suvari, and Mickey Rourke, who reigns over the film because he's the one freak on hand who isn't faking his freakishness.
