One of my favorite horror comedies ever. Treat Williams playing this crazy ass situation straight is just perfect. Joe Piscopo's cheesy failure to be particularly funny actually goes far enough to come out the other end and make it amusing. Extremely appropriate as the idiot sidekick. The special effects are also way way better than you're probably expecting and one scene in particular showcases that in a way that makes me hope those involved enjoyed very active and successful careers later on.
