My biggest complaint was that Jason took over the title, and in the end wasn't that interesting of a character.
Didn't mind the dark Gods stuff, although I'm a bit exhausted with new Gods, old Gods, and dark Gods.
Steve and Etta were minor presences (Etta especially), but at least they weren't completely ignored.
Biggest cardinal sin was Diana becoming secondary to Jason toward the end. I'm definitely ready for the next team to come on board.
