The latest Bourne film manages to maintain almost the same standard as the first two films. I say almost because this isn't as good as the first two. Its certainly action-packed and a non-stop thrill ride from beginning to end. However, at times it borders on parody as Bourne manages to escape from another car crash, or leap from roof to roof completely unscathed. Any sense that this could really happen is lost in this film.
It starts really well (and believeable to) as a Guardian newspaper journalist meets Bourne in London at a packed Waterloo station. This is a great set piece and the best part of the film. After this there are some other great set pieces and a memorable fight with an assasin where there is no background music - another brilliant sequence.
However, the Jason Bourne is indestructible element, and the fact that he seems to get from country to country without any problem (the CIA can control cameras at Waterloo station but they can't catch people at Airports??) makes the whole thing totally inplausible. Now I've no doubt that if you analysis the first two films you can probably make the same criticsm - but I think less obviously so.
So overall this is a classy action film, but its moved away from the 1960's style espionage film that made the first one so unique.
