I'm a huge fan of the first three and while this was a disappointment, I still had a fairly decent time. I don't know what direction I'd prefer, but the storyline was fairly lazy and uninspired, filled with Hollywood hacking and other contrivances Bourne comes to trust Alicia Vikander's character within a couple minutes of breaking into her car to the point that he risks getting flagged upon entering the US and somehow hopes that she's able to hack passport records by the time he arrives / Conveniently just one agent rushes to where Bourne confronts the CIA director even though he knew he was coming, was clearly stalling and has a whole team of security The amnesia plot was tied up pretty nicely in Ultimatum and I don't think it can really be stretched much further as evidenced in this lackluster effort.
On the plus side, there are several standout action sequences, particularly during the beginning chase in Athens and the finale in Vegas. Really riveting stuff. Regarding shaky cam, you pretty much know what to expect going in. If you hated how the camera doesn't stay still even during conversations in Supremacy and Ultimatum, you'll also hate it here. But if you're like me and feel it actually contributes nicely to the unrelenting pace and intensity, and can tolerate the annoying aspects of it otherwise, then you shouldn't be concerned. Paul Greengrass's style is fairly established at this point and I doubt it will change in the future.
All in all a solid, entertaining action flick, not as good as Identity / Supremacy / Ultimatum in pretty much every aspect, but considerably better than Legacy and the end hints at a possible different direction to take the series, though it doesn't really make sense to me. Why the hell would Bourne go back to working for an agency that killed his father and clearly treats agents like him as disposable? He's seen first hand how corrupt they are.
