There was never just one.
As the American intelligence community is being investigated after the events of The Bourne Ultimatum (2007), the CIA try to eliminate everyone tied to one of their clandestine programs… but there is a survivor. The fourth film in the franchise is a reboot of sorts, with Jeremy Renner stepping as a new Jason Bourne, another lethal weapon of a man. He’s an ideal replacement, and the action is exciting, but there’s far too many lulls and characters discussing technicalities. Albert Finney and Joan Allen only have glorified cameos.
