The Q
Hoop’s Villain, Reality’s Hero
Damon has made Bourne, Bourne. They tried to shift the character to Renner but it just didn't work. Unless they put everything to bed in this movie, people will continue to demand more. Problem for Damon is that he's not getting younger and trying to continue the character at the same level gets more and more difficult.
Kinda like Clint Eastwood trying to carry off "The Nameless Stranger" in High Plains Drifter in a remake.
Bourne almost has to be a bit smarter after being out of the 'game' for so long. He and Nicky have to ride off into the sunset.
Or die.
