Darby Crash had the misfortune of O.D.'ing the same day that John Lennon was shot, which explains in part why it took someone so long to do this biopic. Shane West is pretty great in the role, and there's a certain authenticity to mid-sevties L.A. punk scene, but this is sort of a thin, meandering investigation into yet another overly mythologized lead singer who was either a god, a maniac, a moron, or a bore.
