“Bloodthirsty” (*1/2 out of four) was a pretty anemic horror thriller about a struggling indie singer (Lauren Beatty) who begins to have visions that she is a werewolf and is then called to work with a mysterious record producer (Greg Bryk) at his cabin in the woods where she finds out he is a howling werewolf as well and the two of them are destined to be together. Or something like that. Speaking of which- someone at the controls obviously watched “The Howling” a few times before the cameras rolled but this isn’t even up to that film’s campiness or humor. In dire need of a transfusion of spark or energy.
