I found it very disconcerting that the wiggle-camera effect, a potential trademark of the director in the Bourne Identity, detracted significantly from following the movie in the first 1/2 hour. That being said, as the film progressed, the storyline became more complex and I found it to be a satisfying film. Those who think this is Jason Bourne somehow will be disappointed - only 1 fight scene in this one 'starring' Matt Damon, and he lost! He also played a much different character than Jason Bourne, but you end up rooting for him nonetheless. I found it fascinating how they filmed this - looks like it took place right in Iraq, and some of the "civilians" seemed quite believable.
