Vomit, gore, and Christmas. This movie is sickening and relentless, though rather repetitive. Valentine's style seems to be improving, the soundtrack and cinematography are pretty good, and a consistency is maintained despite the bizarre subject matter. This movie also doesn't spend time on pornographic digressions that reduce the tension. That said, the rapid cuts, intended to disorient, soon become tiring. And some shots are too long or clear, revealing the effects to be ludicrously fake, though this is probably not unintended. Of course there isn't much of a decipherable plot, but this movie succeeds in doing what it intended.
