Based on the book, but it is not the book...

Rating: 6/10 (12 September 2004)

POSSIBLE SPOILERS.
For fans of the book, do not watch this version expecting a remake of the Roger Young version (with Richard Chamberlain). It is a well crafted script that is based on aspects of the book, but it is NOT the book brought to film.
Personally, the action was done well - and the chase scenes are among the better vehicle chases. But if there were any attempts to wring any emotional elements from the script, they were unfortunately found lacking.
The other Bourne was more calculating and human, whilst this newer Bourne is a better assassin. Watching both will detract from neither, as they are different enough not to be confused with each other.
