Horror novelist Dean R. Koontz has expressed unhappiness about several cinematic adaptations of his novels (like with HIDEAWAY). Though I haven't heard what he thinks of what Roger Corman did with WATCHERS, I think it's pretty safe to assume that he's appalled, especially since Corman has used the rights to the novel to make several awful movies, including this one. Where to begin? Well, even though the end credits reveal this was filmed in South America, it sure doesn't look spectacular. The various jungle locations look bland and all alike. The story is pretty slow, with not that much jungle action and gore for the first half of the movie. When we *do* see the monster, it's a shockingly bad creation - just imagine the monsters you have seen in 1950s Corman movies, and you'll have a good idea as to how this unconvincing creation looks like. I guess some of the gore effects aren't bad, and it's always good to see Wings Hauser, but the movie ends up being overall a bad and boring imitation of PREDATOR. With PREDATOR freely available for rent or purchase, there's no reason to see this third-rate imitation.
