Currently over 58% of this films votes are "1", probably because it appeared on Mystery Science Theater 3000. While it was great material for the show, this movie isn't completely without merit. The core idea of the movie was interesting (although amateurishly handled), and Micheal Berry gives a decent performance as the protagonist (or maybe the worse actors in the film just made him seem better). Some of the scoring and directing here is effective, as well.
Overall, this film is a 4/10. But if you see it, see it on MST3K. Not only did it make for one of the best episodes (proof that the worst movies don't make the best episodes), but it makes some of the duller parts of the film seem lively.
