To be honest, I don't think this rating is because it's a bad ending. Personally, I think it's because the story progressed at a jogging pace up until the final episode, but then it sped up like a jet plane, leaving the readers behind and ruining everything. If it's going to be an anime original, I'd like to see the scene where Baking Soda gets slapped removed, Tsukuyomi's significance strengthened (at least her true identity revealed), and ideally, a happy ending.

What do you hope for in the anime original content? | yama's post
