And I mean both kinds of “worst.” As @ficuswhisperer said in the Ghostbusters thread:
The only movie I ever walked out on was Shakes The Clown back in 1991. It was a test screening at a mall somewhere in the Valley, so it didn’t cost me anything. Even though Robin Williams was a scream in his uncredited role as a mime teacher, I simply could not bear to watch more than 45 minutes of this pukefest before I’d had enough and had to leave. Since then I’m sure I’ve seen worse movies, but I can’t remember any of them, and I never had occasion to walk out on a movie again.
Now, Neil Marshall’s Doomsday was a complete shitburger of a movie that ripped off everything from Mad Max to Escape From New York and did it pretty clumsily as well, but man did I have fun watching that movie. I’d watch Neil Marshall direct traffic. He never bores me, and his Dog Soldiers is the finest werewolf movie I’ve ever seen. If I were the type to get high, I’d totally toke up and watch Doomsday again right now. It’s my Showgirls.
How 'bout you guys?
