It was funny that they started in ... I guess, middle of the second movie, where he escapes into anonymity in russia. I wasn't sure what was going on, because I remembered the end of the second movie (the name they gave the main character is the exact same as my cousin. I'm related to Jason Bourne!!!), and it was a little confusing.
I did like that they changed the situation, so that when you saw what you thought was one thing at the end of the second movie, it was something completely different when you saw it in this movie. I did like that.
