This is one of those terrible movies that is really good for the guys at RiffTrax to skewer. In my opinion there is still a lot of mileage to be gotten out of "teens in the woods encounter evil possessed killer" plots. But this thing is just such a mess! Other people have blamed the actors, the costumer, the director, the scriptwriter. I'll take a new approach and blame the editor. I see an outside possibility that the script was coherent, but that the editor rendered it into an incoherent mess.
The truth is, after watching the riffed version five times, I still don't quite understand what was going on in the movie. The "rules" of fantasy and horror don't need to make real-world sense, but these rules have to be explained clearly, and then stuck to, and make internal sense. The filmmakers failed at all this.
There is a lot to laugh at here. The wolf attack that did not include a wolf, the terrible acting of the "novelist," the assumption that college students play a lot of hide and seek and truth or dare still, the non- Indian, and everyone mispronouncing the word "wolf."
Poor Corey Haim. Being molested as a kid actor by producers, his drug addiction, and this movie. There must be a special place in the afterlife for someone who suffered that much.
