Oh boy, what a schlockfest. This movie seemed more like an R rated Scooby Doo mystery than a horror picture. There were some horror bits, but it was more comical than scary. The plot is that these early to mid-twenty somethings get stuck on this island which has an old lighthouse. After awhile, they find out that the island has a gruesome history, and a terrible secret in the caves under the tower(lighthouse). Soon, they start getting themselves killed off, and it's really no big loss, as they're a bunch of knuckleheads who you don't care about anyway. The shock ending, where you discover the truth about what's going on, was pretty lame. And the sets seemed like something out of Gilligan's Island. Interesting thing is, almost all the women who appear in this movie, get naked at some point. If you're into schlock horror movies, then you may enjoy this one, but if you like your horror movies to be more substantial, then you should probably pass this one up.
