This movie just did not quite hit me as hard as I expected. Maybe seeing it post-Oscars made my expectations too high. It is a very well done film, but seeing it blind I probably would not have tagged it as a Best Picture winner, myself. The best thing it did was paint a picture of how confusing and conflicting a war such as Iraq is for the everyday soldier and it did a fantastic job of showing the diverse reactions of the soldiers to the war - something that is EXTREMELY RARE in most war movies, which tend to paint a very simplistic and "all of them are the same" picture of soldiers. Finally, it did show that war can be addicting and cause a soldier's values to get very skewed.
While the bad guys are a bit one-dimensional, that is more than made up for by the deeper development of the characters of the good guys. More importantly, I have not been in a theater that had so much audience reaction and emotional involvement since the original Star Wars in 1977. Also, for those folks that don't like SciFic - this is way beyond SciFi - this is fantasy, mysticism and blast you out of your seats visuals. My first thought for a clear Oscar for this picture was not special effects (although it should get that one too) - it is art direction. The sheer volume of incredible images, the number of creatures and their complexity, is incredible. I was blown away.
