“Cannibal Troll” (*1/2 out of four) was a sub-routine horror thriller about a group of female friends (Georgina Jane, Zuza Tehanu, Barbara Dabson, and others) off on a weekend camping trip in the wilderness who become hunted by a beastly troll and they all try to fight back to stay alive. I guess it’s only ironic that a film that boldly rips off “Deliverance” is released the day after Ned Beatty dies. Even “Wrong Turn” told this exact same story with far more shock, scares, and skill nearly two decades ago. It’s horror movies like these that make one want to become a vegetarian.
