Jandy Hardesty’s review published on Letterboxd:
Enjoyable fourth entry into the series, but lacks the weight of the earlier films. There's just no real reason for this to be a Bourne film, and the activities of Edward Norton and his crew to shut down the black ops doesn't feel as connected to Jeremy Renner's attempts to stabilize himself as they should - they feel like they're in different movies, almost.
That said, I love spy crap so much that I was happy to go along for the ride, and having forgotten that Rachel Weisz was in this, it was a nice surprise when she showed up. Renner continues his quest to be in/take over every action franchise, and I'm quite okay with that.
