A DJ plays a record that casts a musical spell. It unleashes dark powers of witchcraft and Satanism. Director Rob Zombie is like an eager film student, flexing his stylistic muscle: one minute it’s arty, then macabre, then trippy, then just silly. There’s an intense soundtrack and a cast of non-Hollywood types, which amplifies the ominous vibe. While there are effective moments, this mashup of approaches lacks any frights or tension…just a collage of creepy.
