Now that the dust has settled and the fifth Bourne film (and Damon's return to the role) has come and gone, and after having re-watched this after seeing Jason Bourne (2016), I can safely say that this is still the fourth best Bourne flick, and a very solid action movie in its own right.
The main reason this is stronger than the fifth one: Tony Gilroy.
He wrote the original film trilogy. He understands the universe of the films, he understands this type of character. He did NOT write Jason Bourne (2016), which was the first and only one in the franchise that wasn't penned by him, and it showed. That movie was much less intelligent and gripping than Bourne 1-3, and this one.
This isn't perfect or as great as the first three. The main problem is that the plot for this installment feels slight. This is literally a throwaway concept (Renner's character and the organization he is a part of are basically being cast under the rug here by the evil US government, and that's the angle). Renner is essentially just reacting to the events in the previous films. It's not quite a sequel because it's actually happening concurrently with the trilogy. Which is a unique touch, I guess, but it destroys any true sense of importance into the proceedings, especially since you hear nothing about the events of Legacy in Jason Bourne (2016). So while this is a fun, well-made film, it inevitably feels inconsequential when you take the entire series into account.
I thought the lack of Damon would be a weakness but it's actually not; Renner is a solid actor, even quite excellent in some roles, and even if he doesn't have the sheer charisma/star power of Damon, he brings his own sense of tough smarts and cool wit to the film, and he does a really good job of communicating the same sense of constantly-three-steps-ahead that Bourne himself did. Renner has that same natural air of intelligence as Damon, but in a grittier fashion, and Tony Gilroy knows how to utilize it.
Rachel Weisz doesn't have a whole lot to do but she has her plucky moments and at least plays a heroine with some intelligence, and who isn't simply a love interest for the protagonist. I actually think Gilroy handled that part well.
Here's hoping that if they make another Bourne installment, Tony Gilroy comes back as the writer. And I would gladly see Renner continue this role, but it probably will never happen.
