I think "Precious" "Avatar"or "A Serious Man" should have won over "The Hurt Locker"
My personal favourites of the year were Inglourious Basterds, Avatar, and Zombieland.
But then again we all have varying tastes. I'm no great movie critic, but I do have a great appreciation for good filmmaking. I think that "Blackhawk Down" or "Jarhead" were far better examples of what a war zone does to people.
As far as the main character in the Hurt Locker, if he was in my section, he would have been pulled inside the wire at the first hint of any "cowboy antics" I just felt that main part of the storyline was unrealistic.
my 2 cents
