One thing that I give kishi props for in my book is offering Oro. It was something that needed to be done for the longest time. Feels like finally one of the biggest open plot lines in naruto has finally been drawn to close and now the storyline has more breathing room.
Although I must say I'm a bit disappointed with the lack of akatsuki character development. Honestly I was really curious to hear some hint of a back story for Hidan and Kuzuzu but that doesn't seem like it's going to happen any time soon. Same goes for Zetzu, Diadara, and kisame.
