Other than a few bits and pieces, this movie strays badly from Ludlum's artistry. However, if you've never read the Bourne series, or if you're willing to forget the books, then this is a great little movie. Matt Damon does a fantastic job playing the part of the amnesia suffering hero, Jason Bourne, who at every turn finds out things about himself that leaves him increasingly aghast - like the book, the movie makes a hero out a character that would be a murderous thug in any other setting.
Franka Potente plays the part of the mystified free-spirit who befriends Bourne (enticed initially by some cold-hard-cash), and eventually becomes an enthusiastic confederate. I suppose it is too much to expect a movie to capture all the intrigue, maneuverings, clandestine subterfuges and treacheries that Ludlum wrote into the books - and it is probably proper that the movie really doesn't try. It never could capture 10% of the first book in the length of the video - let alone the whole series -- but still this well worth seeing. I do miss Ludlum's Jackal, but there's still lots of action, good technicals and not too much gratuitous vulgarisms, as well as superb acting. Good high-drama flick!
