The problem with Avatar is that its an epic movie watching adventure, but then that's it. It's like a roller coaster ride. They're fun, and they give you a rush, but you don't spend your day to day life i eager anticipation of the next time you'll ride. Avatar is a visual experience- similar I imagine to what the first IMAX experience was years ago. But once you've seen it, you've seen it, and as momentous as it is, it's over.
My vote would go to Hurt Locker. It's the war movie of the decade and not because it simply tried to be. March 7th 2010- K. Big. or go home!!
