Rise of Planet of the Apes. Surprisingly good.
Star Wars I to III on Blu Ray. These movies actually get worse with repeated viewings. I'm not even a huge fan, but it pisses me off how somebody could butcher a cool concept so badly. You've got everything going for you - cool Star Wars stuff like light sabers and crap, great actors (except for a horribly miscast young Anakin), unlimited money and production value - but without a good story or dialogue, its just steaming pile of dog crap. Contrast with Rise of Planet of the Apes. Cheesy concept, but an entertaining, well crafted story, and it ends up being a good movie. What a shock.
Cowboys v Aliens. See above. Great actors, great effects, stupid story = crap movie.
Half of Black Swan. Gave up. This movie is boring and disgusting. Just don't want to watch some crazy chick masturbate, get raped, and cut herself, even if it is Natalie Portman.
