House of Blood (aka Chain Reaction) - A bit of gore here and there makes it fun, but the story is pretty forgettable stuff.
Think of how the vampires from the Titty Twister now live in a old timey house in the woods. And ever so often, a bunch of prisoners drop in from the worst prison transports ever. (Soooo... Anyone on the care list? Not really.) I'm pretty sure there is something at the end that was supposed to be a twist, it's just that by then I was too zoned out to care.
