Well, if I had a vote for best picture it would have gone to Serenity, Sin City, or the 40 Year Old Virgin...but the academy's idea is much different. Usually between some well known movies and some artsy-fartsy stuff that people don't go out and see untill they hear "oh, this is up for oscars." The best movies are usually the most fun.
With that being said I really liked Crash. It wasn't all about racism. Just pointing out that EVERYONE has a good side and bad. I liked it, but it's probably at the bottom of my top 8.
