Too long. The action scenes and back and forth between the protagonist and antagonist got boring and repetitive. Some scenes, specifically from the POV of

the American government

felt confusing and unnecessary. The action was reminiscent of the previous books, and was still enjoyable. It felt like the book wanted to focus on a mental health aspect, but kept abandoning it and then picking it back up at other points in a jarring manner. Certain scenes felt like they were placed in as token recognition, like when

Bourne helps Conklin put his fake leg on. It happens twice and is not referenced anywhere, which makes it feel like forced character development except I don't know what was supposed to be developed.
