interesting that it was directed by Kathryn Bigelow whose films I'm a fan of - Point Break still kills it nearly 20 (!) years on - she brought that same twitchy nervous constant motion style to a much more serious topic, the Iraq War, & managed to fuse it w/a pretty high level of emotional complexity. keeping politics out helped a lot as well. the acting is largely fantastic too, all the principals certainly & a bunch of the cameos as well. hiring displaced Iraqis (it was filmed in Amman) to play the Iraqi roles & extras was a good decision.
I dunno I guess it really kicked up a lot of feelings in me - rage, sadness, but above all shame. The other day a friend emailed me a quote from a British counterinsurgency advisor to the effect that "the U.S. military is better than the country it serves". I reckon that's well true. Much, much better than the country it serves.
a few more thoughts on war movies (& hopefully some discussion) here for anyone interested
