The Bourne Legacy
The Bourne Legacy spends a lot of time setting up the shared universe, and the implications and consequences of the events surrounding the previous 3 Bourne films in this installment.
So much so that it almost overshadows the action in this one.
The Bourne Legacy focuses on a parallel program called Operation Outcome, headed by Eric Byer (Edward Norton). The program aims to enhance the physical and mental abilities of their field agents through ingestion of pills.
As Operation Blackbriar and Treadstone Project gets increasingly out in the open, Eric decides to burn the operation to the ground, and remove all traces of it. As a result, all personnel exposed to Operation Outcome are killed with the exception of Aaron Cross (Jeremy Renner) and geneticist Dr Marta Shearing (Rachel Weisz), coincidentally the most beautiful scientist in the entire program (Seriously, how does Rachel Weisz manage being 42 and amazingly beautiful at the same time?? Look.).
Then, Jeremy Renner and Rachel Weisz spend the rest of the movie dodging bad guys as foreplay.
Not as tight as the original trilogy, but still plenty watchable.
