Able Archer 83
Two Minutes to Midnight
Graffitti Bridge - one of the worst movies ever filmed.
I caught Graffiti Bridge for the first time a couple of years ago, and I was stunned at how bad it was. There was not a single good artistic decision evidenced in this film; everything was awful, from the lame music, to the cheap sets, to the "acting", to Prince's beard (probably the worst thing about the movie).
I went on a Prince forum, and did a search to see what they had to say about it. His stans were shytting on it left and right. If his fans--people who eagerly snapped up every piece of trash Prince produced--hated it, that should tell you how awful it was.
Back to the topic at hand, I would say Ice Pirates. Me and my dad went to see it when I was a little kid, and we thought it was terrible. The only redeeming thing about it was the trailer to Ghostbusters played before the movie.
