My only issue is the death of a particular character (won't spoil it for you). It wasn't done well and I'm wondering why they bother to kill this character in the first place. It seems a shame they could have just let that character be and fade into the unknown. Not my decision though. Ok wait I have two issues - the second being that every CIA head seems to assume that JB is behind everything to do with Treadstone & the black ops programs even when there's no evidence and I know they do it for plot conflict but it's unwarranted for this particular storyline. Again I didn't write it.
Other than that...ya go see it because it's an amazing action film and if you like that you'll LOVE Jason Bourne - who doesn't?!?!?!
