Nor does it delve deeply into some obscure theory of science or arts, bombarding the viewer with ideas he couldn't have come up with himself. When I say 'intelligent', I don't mean it to be cunning, surprising the viewer with unsuspected plot Which is a shame, as it's only after about 20 episodes that this series progresses from something that is slow, somewhat overly bombastic, and hinting at more to come to show itself to be one of the most intelligent pieces of anime that's been made to date. That is to say, with 110 episodes, your vote only counts after you've seen 22 episodes, almost a full season, and those who don't like this show probably won't wait for 22 episodes to decide.
