Insanitarium

The premise of this movie is that a man gets himself committed to an insane asylum to rescue his suicidal sister. What he finds is that a mad doctor is injecting his patients with a new nano-tech drug that turns patients into cannibal vampire killers. This is the setup that allows about two hours of unremitting gore.

The saddest thing about this is the participation of Armin Shimmerman of Star Trek. He's actually a good actor, and he spends all of his four scenes on the same set. They probably only had him for a day, and had to work him into the otherwise meaningless plot.

It's not a great movie, it's typical of its genre. It has some interesting performances and some good production values, but honestly, I didn't really care about the characters and don't see a reason for you to.
