Metalheads: The Good, the Bad, and the Evil (2008)

Synopsis

We're thrown into a world of metalheads unlike those in Hollywood. Mainstream movies about metalheads are actually showing you posers, not metal people. Hollywood only understands the mainstream, so their idea of metal is the pop and glam garbage. In the words of slacker Bill, the only time that a song should have the word 'baby' in it is when the song is about killing babies.
