If you share the all-American politics of the film or don't care about politics, you'll probably find this more enjoyable. None of the locals are portrayed sympathetically and none of the operatives are sympathetic. This is probably quite true to life but they could have had a portrayal of a Middle Eastern person who wasn't a terrorist or a deserving victim.
As a docudrama, it sort of works, but it never goes beyond the docudrama mentality. Maya remains a blank throughout and moments of characterisation are sparse. Characters are clearly not writer Mark Boal's or director Kathryn Bigelow's strong point and I was longing for something that might provide some drama rather than a re-enactment of something which we already know the outcome of. The ending hints at this but doesn't really push it. I'd like to think that the ending showed Maya as unsympathetic but I'm not sure Bigelow is subtle enough for this.
Its lack of a balanced political viewpoint and proper human drama, despite having an unnecessary two and a half hours, means that it's not quite the definitive epic it wants to be.
EDIT: I just have to mention the John Barrowman cameo. It was about halfway through the movie and I was holding out for a little bit of drama to break the blow-by-blow dubious docu-dramatic narrative. We were in a room of CIA agents and I notice a man who looks exactly like John Barrowman. Then I realise that it IS John Barrowman. Maybe he might sing. But no, his cameo consists of him going into an elevator with the protagonist and saying one innocuous line. Could this be the most bizarre and pointless cameo in film history?
