i voted 300 but it's a very close call with bourne! simpsons and ratatouille gets mentions as well

300 - gore,action,cinematic and to me, stunning visuals
Transformers - i must say i was disappointed(maybe cos of the hype) but i didn't like the designs and i thought the story was utter crap
Die Hard 4.0 - pretty fun to watch
Stardust - it was pretty decent but it wasn't anything special
Ratatouille - i liked it, very interesting story and heartwarming
The Kingdom - comment n/a
The Bourne Ultimatum - lives up to the bourne franchise,a nice storyline and storyline, camera action(presonal pref) and of course matt damon was just brilliant
Ocean's 13 - was so so, watched it on the plane so i cant say much
The Simpsons Movie - the 1st big screen film for the yellow people! pretty nice, esp spider pig!
1408 - havent watch
Hairspray - very nice,certainly lives up to the hype,very good lead and a stunning performance by travolta
Harry Potter and the Order of the Phoenix - since i didn't read it, it was pretty good to me.
Spiderman 3 - decent but getting overly emo

2007 is not over yet with releases like golden compass

and not mentioned here is Hot Fuzz!
