For those yet to be traumatized by Troll 2's terrible acting, the terrible special effects, and the terrible writing, you'll discover that in the calculus of bad-film equations, the movie's foibles make for one hell of a good time. Seeing it outdoors thanks to Rooftop Films will only add to the fun. If you can't get enough green blood, come back the next night to see documentary Best Worst Movie Ever, which catches up with the production crew and the cult following that Troll's misguided work inspired. Your Troll ticket gets you in for free.
