My personal belief is that in about ten or twenty years from now, The Bourne Trilogy will be regarded as one of the all time greatest action sagas. The intriguing setup from The Bourne Identity, the conflicting morals of The Bourne Supremacy, and now the balls to the wall climax of The Bourne Ultimatum. If I could describe this action masterpiece in one word, it would be - in all caps - EXHILARATING!! Picking up a few weeks prior to the end of The Bourne Supremacy, Jason Bourne is trying to escape Moscow. Meanwhile, in London, a journalist named Simon Ross (Paddy Considine) is publishing stories that slowly reveal Operation Blackbriar - a more lethal offshoot of Treadstone, and the CIA essentially want him dead or silenced. Once Bourne learns about Ross, he seeks him out hoping to find the missing piece of his identity: who recruited Bourne and who made him the precision killer that he is today?
Realizing just how much of a threat Bourne is to the CIA, the new agent Noah Vosen leads the chase in trying to catch him, against the persuasive influence of Pamela Landy (Joan Allen) who is in some indirect way Bourne's ally. Both of these characters create just as much excitement in the scenes behind computer screens and controlled towers tracking Bourne's whereabouts as the scenes where Bourne is fighting his assassins.
And what fight scenes they are!! The choreography is more complex, faster, and constrained to even tighter quarters than in the previous film. The camera has an even shakier, documentary styles look, resulting in jaw dropping, exhilarating (there's that word again!) car chases, hand to hand combat, gun battles, rooftop chases, and seek and destroy sequence with Bourne and Ross in a crowded mall that will have your eyes glued to the screen.
Nothing more can be said about Matt Damon other than a lame joke like "he was 'bourne' to play this role". Without Damon's likability this trilogy would not have worked half as well as it has. He has helped create one of the most fascinating and legendary on screen assassins that have graced the screen since James Bond. Simply put, The Bourne Ultimatum is the very definition of a perfect action picture. It's the most fitting end to a great trilogy, and an action film to which all espionage action films from this point on will be compared to.
