I saw this movie about three years ago on a defective rental tape, and I must say that I was shocked. I was shocked at how a film dealing with supernatural rape and mutilation can be so...conventional! Yes, you read it right. When the screen isn't gushing blood at regular intervals, the movie is actually a run-of-the-mill slasher-mystery, with stilted dialogue and unimaginative presentation (though the movie-theater sequence shows some flair). And talk about your surprise endings!
The acting is bland; even John Cassavetes (who I guess had some bills to pay that month) seems preoccupied. In fact, despite the aforementioned brutality, the production seems altogether too restrained. It's as if, despite the lurid subject matter, the filmmakers didn't want to make an exploitation picture--even though they can't make the material work on any other level. As a result, the more sensationalistic elements are balanced out by indifferent "human drama" involving a bunch of not-very-interesting characters. The occasional stabs at depth ("I don't WANT tenderness!") range from just plain ineffective to full-out laughable. But the final product (which cost more than you might think) isn't laughable, but merely mediocre. It did have potential, but instead it just sort of...is.
