This film is not for everyone, but it is a well-made film by a hot director and one of my favorite Hollywood actors. This film makes no effort to hide its' position on the reasons for going to war in Iraq. That may be unacceptable to some, but what can't be denied is the pulse-pounding tension and a solid cast that sells the story. I would have given it 5 stars if given the opportunity, if not for the clear good guy/ bad guy delineation we've seen many times from Hollywood. The good guys were angels and the bad guys were unscrupulous and hell-bent on corruption and lies (see Kinnear's character). This does not represent real life IMO, even though I agree with the premise of lying about WMD.
Overall, I would definitely recommend this film to other with the caveat of maintaining and open-mind and, depending on one's view, maintaining one's emotions.
