Started off at a great pace, with lots of mystery and interest. Starts to taper off around the middle, and is pretty predictable and stale throughout. One of the few examples of where the film is better than the book.
A very readable thriller about an amnesiac attempting to regain his memory, all the while suspecting he may not be the "good guy". If you are only familiar with Jason Bourne through the films starring Matt Damon you may be quite surprised by the novel. Hollywood (as always) felt compelled to tinker with some of the major plot points.
