This is a very entertaining film, simply as entertainment. Well paced, well scripted, well acted and very well directed by Paul Greengrass with his recognizable "Bourne" style of swift, sharp, clean, and lots of action. There are no real standouts acting-wise as this is an ensemble effort, though I particularly liked the fellow who played their Iraqi helper.
But is it true? The plot is basically saying that the West went into Iraq purporting to be looking for Saddam's WMD's, but already knowing that there were none. But when Saddam's son-in-law defected to Jordan, he brought crates - not just one, - but crates full of documentation regarding the WMD's. General George Soda of the Iraqi Air Force has publicly stated that before the Western armies arrived, 56 passenger aircraft were emptied of seats etc., and loaded with WMD's and flown to Syria. (I suspect myself that there were probably more buried where they could not be found, but as yet, we don't know that for sure).And even if they did not find any at that time, does any rational person believe that there never were any in the first place?
Which brings me to my next point, which is that there is a subtle undertone in this film that Saddam was not really such a bad fellow after all, and we were too hard on him really. (Read some actual accounts of people who lived through his dictatorship and it is obvious that he was a barbaric monster with the power of life and death over every citizen of Iraq, and he ruled by absolute terror.) There is also a rather anti-American, anti-West spirit which prevails throughout. I am rather weary of this "West bashing" which one sees so much of now, and it is not only foolish PC rubbish, but also not historically accurate. Western countries have much to be proud of, and if we all knew our history better, we would be aware of that fact.
