Rated PG-13 for action movie violence
First, it helps to have seen the other 2 films so you have a bit of backstory. There are some plot aspects that require you to remember why Bourne is on the run and who he has previously interacted with. Not necessarily vital, but helpful.
Secondly, I’m not a fan of the shaky camera filming style that was overly popular in the 2nd film. It’s used way too much here, making it hard to focus on specific action sequences.
Third, if you’ve seen the first two films then you’ve pretty much seen this one. No big surprises. The film does start slow, but once it hits the first action sequence, the film rolls along pretty well.
All that said, the action and stunts were well done and entertaining, and the plot and dialogue were relatively approachable and occasionally funny. Overall, more believable than the stuff in Die Hard, but only slightly better.
Did I enjoy the film? Sure. It’s good and worth the trip to see it. I just wanted to like it more than I did.
Would I have enjoyed it more if the three points above were addressed? Yes.
