I work at the movie theatre... Go see Time Traveler's Wife. Inglorious is really long and really gory, not to mention there's a TON of subtitles. The Proposal is really funny, and G.I. Joe is decent, but Time Traveler's Wife is really original and Rachel McAdams is awesome.
GI Joe was Craptacular. I expect Basterds are the same, but I heard good things about it and will be seeing it tomorrow. Not really a fan of Tarantino, but HEY! I don't expect much from it other than a laugh, lots of blood and gore and lots of rubbish. So I should enjoy myself.
I voted Time Travellers Wife, only because my partner so loved the book, and is a chick flick.
Ponyo was light-hearted, cute and sentimental, in a Japanese sort of way.
Inglourious Basterds was awesome. They play up Brad Pitt in the commercials but he isn't in it that much. There's about three intersecting storylines so he has about 1/3rd screen time, if that. It's Quentin we're talking about here, so there's a lot of dialogue, followed by some extremely gory killing of course. I think if you liked Kill Bill there's a chance you might like this.
I didn't see the others so I can't really say.
I also agree with some other comments, so if you haven't seen District 9 you should, and Ponyo was cute, weirder than Miyazaki's usual stuff, but cute. Tina Fey voices Sasuke's mom
