I actually really liked the ending. The majority of the fandom seemed to expect to see the familiar faces of E7 in AO, and that obviously wasn’t the case. But that’s okay, because the show is about Ao, not his parents. I would’ve liked some final confirmation on Renton and Eureka really being okay (thanks for the loose end, BONES), but I’m okay with this ending. It essentially stands on its own apart from E7, and I like that. Also, I love Ao’s surfer hair. That’s all.
