Absolutely laugh-out-loud terrible. The best part is that it doesn't know how bad it is. The movie actually thinks it's being clever or artistic, and it tries so darn hard and does it so, so poorly. The closing monologue by the mad doctor is amazingly over the top and hilariously asinine. Make no mistake, however; this is not in the "so bad it's good" category. This is just bad. Great to make fun of, certainly, but also very, very bad.
