Okay, TROLL 2...a movie so bad it's good. Literally every aspect of this film is bad. But, you also can't take your eyes off of it. I'd compare it to BLOODY MURDER. A movie that takes itself so damn serious but has no right to. Also, be sure to check out the documentary BEST WORST MOVIE, which chronicles the current state of TROLL 2 love.
