Inspired by the grays on the MP

What movie do you absolutely hate? Doesn't have to be one that's popular or critically acclaimed. What movie have you watched and hated so very much that you wished you could sue the movie studio for time back?

For me, it's pretty much almost any Lars Von Trier movie I've been suckered into seeing.

Oh, and the Lindsay Lohan classic "I Know Who Killed Me"

ETA: I forgot how viscerally I hate The Green Lantern that I blocked it from memory! I didn't even pay to see it and I still want money back!
