I think they may have a third one in which he finds out more about his identity.
It was a good movie, but, I think the first one (the Bourne Identity) is better. What I didnt like most about it was just the camera angles and the way it was shot. At some points, like during one fighting scene, the camera is all over the place and its hard to see exactly whats going on. Overall though I still liked it, but I dont think it was as good as I thought it would be.
