Epic Movie holds the unique distinction to be the only film I've ever walked out of a theater before it was over. It was that bad.
When A Stranger Calls was equally as bad, it was predictable, bland, and failed as horror.
Napoleon Dynamite wasn't funny.
I don't like Borat much. Not because it was offensive, but because I didn't find much of it funny. Okay, this guy's a little backwards and his culture's out of touch. This is humor?
And finally, the one I'll get hate for. 300. A movie so... I can't even put it into words. The SPARTANS get turned into people who hurr hurr at "boylovers", the horribly deformed, "imperfect" character is the corrupt traitor, and the main villain is evil for no adequately explained reason. When the action finally arrives, it's slow-paced, with overtones of right-wing propaganda smeared allll over it. I'd rather watch an Uwe Boll movie. At least those can be made fun of, rather than making me grimace.
