The first arc is pretty fun and beautiful. Great show of what the character is about. The second arc is too long and has the problems with lots of Brian stuff. I think the Civil War II tie-ins are very interesting and have their sad moments. I actually really enjoy Riri's year on the book. Just good comic bookin'. The last year of the run was a disaster, though. Just a boring slog for issue after issue to hit #600, with all these major things dropped towards the end with no time to breathe. It leaves the big finale as kind of a mess. Although, I do cut Brian slack since some of that stuff happened when he almost died.
So, adding the first arc, the CWII arc, and Riri's year vs Infamous, the second arc, and Search For Tony Stark, I really like half the book and don't like half of it. Don't really feel so split about anything else.
