An expansion of the universe from Robert Ludlum's novels, centered on a new hero whose stakes have been triggered by the events of the previous three films.
Jeremy Renner plays another secret super agent like Jason Bourne, who realizes he's been targeted for elimination. To save himself and the experimental medication that gives him great physical and mental power, he travels from Alaska to Manila, fighting off wolves, drone missiles and assassination, while hooking up with Dr. Marta Shearing (Rachel Weisz), a biochemist who knows all about the medication. The action scenes are gripping in the moment, but go on too long and don't add up; the dialogue scenes (with Edward Norton, Stacy Keach and Scott Glenn), are well-acted; the plot is a murky muddle. - Two and a half stars
