Closer - even a stripping Natalie Portman couldn't stop me from turning off this movie before the unbelievably pretentious dialogue made me jam a screwdriver into my brain.
Ocean's Twelve - I loathe this movie. You go through 95% of the movie following their heist, then in the last 5 minutes they go, "Ha, ha, just kidding, here's a scene that occured at the beginning of the movie that we didn't show you that makes the last 2 hours a complete lie." It's 10x worse than the "It was all a dream" ending.
The first two Star Wars prequels were completely awful; the third was 10x better, rising to the level of: meh
