Brilliant. A polarizing point of view for sure considering the general consensus on this anime. But hear me out. Let's start with the good. The creative concepts and whimsical laws of nature of the world are really a breath of fresh air. In Hollywood terms this would have been similar to acclaimed shows of novelty such as James Cameron's Avatar. The show is a blend of character introspection as well as plot/action driven, with slightly more emphasis on the character development. But while these are genius takes, it is also the reason for much of the hatred this anime gets. For one, the free flowing ideasof themes and alternate reality world building laws, while brilliant, is considered by many as a flaw for not being explained well enough. It doesn't follow the natural formula of anime that explains new concepts when introduced to the viewer(even though on world they have no reason to do so)

Instead the viewer is meant to have their own brain fill in the pieces and just accept that the current going ons are just fact without explanation. And this is the major source of contention for many who dislike this anime as it doesn't spoon feed them enough. Like Sol Stein said, as writers some times it's best go give the audience the envelope, rather than tell them the contents inside.

The second reasoning is the pacing. It's breakneck. And while jarring in most animes, I find it FITS this creative world so well. Rather than being disjointed, it feels like a purposeful creative direction.

In my own eyes I find it one of the absolute underrated gems on anime and the low rating is due to society's growing brain rot problem
