Go see Up. And maybe The Hangover too. It wasn't "OMG BEST COMEDY EVER" like some people were saying, but it was still pretty damn funny. Also, rent High Fidelity. Far and away Jack Black's funniest role.
I don't plan on watching a ton of movies this summer, but I am going to try and get through at least Season 7 of The X-Files. I'm almost done with Season 3. I am very excited for Public Enemies and Inglorious Basterds, though.
