I was so excited by Titans Hunt, and had a feeling it was leading to the return of Wally. I think the story made it kinda evident. There were elements of Abnett's story I liked, but I think he mostly dropped the ball. He may have had his hands tied by editorial. The ongoing that followed was even more disappointing. Then editorial stepped in again and changed the line up -- and I dropped the book.
I'm very happy that World's Finest: Teen Titans is a thing. It's the best Titans series in 10 years or more. Hope it continues. I guess will have to end at some point -- since the team would eventually disband before forming the one with Starfire, Cyborg, Raven, and Changeling.
