From The Movie Snob
The Bourne Ultimatum (B+). For what it is, this movie is very good. Matt Damon (The Martian) reprises his role as Jason Bourne, a man who has lost most of his memory but possesses a startling array of skills that would be characteristic of, say, a top-secret CIA agent of some sort. As in the first two movies (as best I can recall), he’s on the run from the CIA because some top brass are afraid that Bourne will spill some of their ugly little secrets. But plot is almost superfluous; what counts are the action sequences in which Bourne must outfox his shady pursuers over and over again. These chase scenes are even more over the top than in the last movie, but everything is filmed so convincingly that I just sat back and enjoyed the ride.
