Some good movies out this year for sure.
The two I have seen this year are:
Terminator 4 - I think this one might take the cake, although Im a bit biased...see sig
Transformers 2 - Excellent movie, actually better than the first one I would say. Man that megan fox!
I want to see by summers end:
Harry Potter Half Blood Prince - my girlfriend got me into the books when this book(the 6th of 7) came out(after making fun of her for being such a nerd about them), I actually really enjoyed them! I will be seeing it next week most likely, it comes out on my bday!
The Hangover - This looks hilarious and friends of mine that have seen it say its as good/funny as the previews make it look.
I also remember seeing some sweet previews while at the theatre this year. M. Knight has a new movie coming out (i think for summer 2010) You either hate or love this guys movies, I am usually at least intrigued.
