If you're expecting James Bond, or even Jason Bourne, you've come to the wrong place. This is a brutally realistic film about how both sides in the so-called 'War on Terror' bend every rule of civilized conduct in order to further their own questionable ends. It's a story about people who have absolutely no doubt that their ends justify the means... even though those 'ends' long ago ceased being particularly noble, if indeed they ever were.
The story concerns the journey of one Middle Eastern man from political agnostic to suicide commando. His compelling, if fairly obvious, tale is counterpointed against the gradual awakening of the British assassin sent to track him down, operating well outside the rules of police work or even espionage.
There are no laughs in this movie, no car chases. There is extreme violence, and a lot of incentive to question the purpose of that violence. The characters are strong, as is the message. Unfortunately, those who most need to hear that message are likely to either avoid this film entirely, or conveniently misunderstand it.
