I thought it was well made with a small budget. I like the war junkie archetype, like Hoot from Black Hawk Down or the prayer saying sharpshooter from Saving Private Ryan, it plays well in a fictional character. Like most war movies, I didn't like the slow introspective segments that attempt to humanize our warrior friends. That pattern is so tired: action, soul seeking, action, soul seeking, action, soul seeking. The action was brilliant and suspenseful though. Very sharp acting.
It also did a good job of painting Iraq as a tangled up situation without getting into policy issues (which any movie would necessarily need to gloss over and therefore do a disservice to) and without making any overt statements about the overall war other than that things are messy. It wasn't the Best Picture of the year, but I've long ignored the Oscars when it comes to passing judgment on films.
