In order for me to tell you what is good about this movie, I have to explain what is wrong with it and that is the fact that you get the feeling fifteen minutes into the film that there is no reason for it to exist. The last film (Bourne Ultimatum) pretty much closed the book on the series, with little to no wiggle room for an encore.
This movie feels like a studio trying to milk dried what was good from the original trilogy in order to make more sequels. The bad part is that they did it in the most unbelievable way, so much so that you really need to forget what you saw in the last three films in order to believe what was going on in this movie. Tony Gilroy (Who wrote the first three movies) directs and writes this one but falls flat on his face with halfhearted explanations that try to justify this movies existence. Not to mention the fact that the villain of the movie is a lightweight compared to what came before him plus the glaring fact that Edward Nortons performance as the heavy is pretty much phoned in. He does not have the confidant arrogant swagger that Chris Coopers character had in the first film nor the desperate menace of that Brain Coxs character brought to the second. Nortons character is more in line with the villain of the third, who was played by David Strathaim (who has a cameo in this film).
But after all the conspiracies have been unmasked and the last bullet drained, I still couldnt help but miss Damon in the lead role. We all knew how great he was as Jason Bourne, but it would seem that I at least took his work for granted, perhaps failing to truly appreciate how magnetic he was in his ass-kickery. Lets hope Damon comes to miss his involvement and teams up with Renner in future missions, because that would be an on-screen duo worthy of all kinds of legacies.
