OK, I've read quite a few comments saying this was the worst film they've ever seen... obviously you haven't seen too many films if this one is at the bottom, try Gothic Vampires or others in the same league, then you'll see really bad.
This movie wasn't supposed to be scary or too serious, it was meant to be a spoof with some dumb ideas backing it it to make the audience laugh. Didn't the shirt the big black guy put on in the middle of the film give that away... not to mention the craziness at the end. It wasn't the worst, but was definitely down there with the rest of the B-genre films. If I had friends who wanted a non-serious, lets make fun of it while drinking or having a good time, I'd mention this just for the off-beat crap you see in it.
