I just watched The Devil's Rejects... →[More:]and I have gotta say, that that is one of the worst movies I have ever seen in my life.
SPOILER
Do you realize that the end of that movie involves watching the main characters sitting parked in front of a roadblock for literally 5 whole minutes because that's how long the slow part at the beginning of the long version of freebird takes to get to the guitar solo? Then they get shot by cops in slow motion to the guitar solo from freebird. Lord, I wish I were kidding.
END SPOILER.
that said, what's the worst movie YOU'VE ever seen? and campy hysterically bad ones don't count. I'm talking unwatchably bad, no redeeming value whatsoever.
