Well, that was probably the most self aware horror film I’ve seen since Leslie Vernon : Behind the Mask, or Cabin in the Woods. A supernatural serial killer, called Mr. Bonejangles, our titular villain, is being transported to a mental hospital, when his transport gets interrupted by a zombie attack. His escort wanders off, and Bonejangles does his killer thing. So, the zombies are part of a curse by an evil witch.  This movie has some of the best moments. Including one dude, after his hand is amputated, trying to pull the Ash Williams chainsaw upgrade and dropping the saw into his own body. I’d say this one is worth watching. It’s just wow; so surreal.
