Not sure why I like the Bourne films. Typically such flix are not my cup of tea, but somehow these satisfy.
The Bourne Ultimatum is the least interesting of the three, but it's still great fun. The plot? Fight scene, car chase, fight scene, foot chase, fight scene, car chase, motorcycle chase, rooftop chase, fight scene, car chase, foot chase, fight scene, brief expository sequence with backstory, fight scene, car chase, unsubtle Abu Ghraib/rendition/waterboarding references, fight scene, explosion, car crash, fall, resolution leaving door open for the fraternity of writers named "Ludlum" after the true Ludlum's death to churn out sequels in perpetuity.
Note to film-makers: stop the camera sometimes. It doesn't need to drift and jitter continuously.
Is there a more un-interesting actress than Julia Stiles? Christ, she is more wooden than the cast of my high-school's production of Guys and Dolls, and has no charisma.
