Bourne got stale, Renner unstaled it, Damon came back.
Some stuff wasn't touched on in 2016, like the pharmaceutical resources used in legacy, but creepier possibilities were brought in. When vikkander wants in on the bourne hunt, Tommy Lee Jones says she hasn't been "indoctrinated" on the project, which gave me mass effect flashbacks. TLJ also turns in an outstanding performance as a soulless suit, but I could have done without the stupid "cut vikkander out of the loop" bit. I won't say subplot, because it's a bit, and the writers should be ashamed of it, along with the snowden and "deep dream" cowpoo.
I kinda want to see Damon and Renner square off, but I think that's because I hate hawkeye, over in the MCU. Stark made him not be deaf, and allowed him to retire from shield, the ONLY shield retiree under the hydra administration, and he shot Tony's son (vision) and acted like a bless'ed bottom.
And who says legacy isn't a prequel, maybe shield offered cross (renner's bourne) an out? Treadstone is definitely hydra level evil.
But that's fanon nonsense.
2016 bourne ended with the traditional "I'm smarter than you" bit, which makes no sense. Bourne knows vikkander is as much an evil suit as TLJ, trying to pull heartstrings, and reveals that he knows. Which makes no goddamn sense if you're trying to play evil shadow game.
