A lot of folks are quick to state their favorites, but what films did you absolutely despise (by genre)? Granted, "The Keep" did not live up to the novel, but it was far from the worst.
Me first:
Science Fiction: "Maximum Overdrive." (Steven King is turning in his grave. But, he's alive. This will kill him!)
Western: "The Misouri Breaks" (Marlon Brando in a dress!)
John Wayne: "The Conqueror" (The Duke as Ghengis and Endora as Mom. Shot at an A-bomb test site, this killed a bunch of the cast, eventually.)
That's just off the top of my "head."
