Writer/director Paul Haggis follows up his string of Oscar-winning efforts (Crash, Million Dollar Baby, Letters from Iwo Jima) with this slow, somber, war-weary murder mystery. Tommy Lee Jones gives a brilliant, understated performance as a patriotic, long-retired MP who goes looking for his AWOL Army son. Contrary to expectation, the film doesn't preach against the Iraq war. Instead, it's a thoughtful rumination on sending young men off to war--any war--and the effect that has on them when they return. The film isn't a thriller by any stretch of the imagination, but it boasts some fine, sympathetic performances. 122 minutes R.
