Query: Rent it first

I consider myself a fan of sci-fi/fantasy stories but I found this movie laughable. The first 1/3 of the movie looked promising but the plot just took a nosedive. It just reminded me of one of those hokey sci-fi channel shows that never became successful, or an episode of the Twilight Zone which got scrapped.Unless you're a diehard sci-fi geek don't buy this movie, rent it first.
