Deathgasm

Brilliant title, thoroughly entertaining film. I was never once bored watching this horror comedy. 

The story is fairly basic, with a metal band summoning demons and then having to fight them off, but that's not at all a bad thing. It reminded me quite a lot, especially how freely the gore flows, of The Evil Dead franchise and Peter Jackson's early two movies Braindead and Bad Taste. I love those films and this is nearly up there with them. The characters were interesting, the gore was great and it was so much fun. 

Highly recommended.
