Seems like the same crap as the S2 of this anime. People tend to say that everyone hated it because "they fired the guy who made season 1", but let me tell you that when I watched it I knew absolutely nothing about this and I still got angry / sad / disappointed just because of how bad the story was when you compare it to the first season.. Really don't know why they're now making a manga out of this garbage. They could've made a manga that would have different story than the anime, just like the first manga which was also different from the first season of the anime, they could've attempted to make a good story that would continue where season 1 ended and hopefuly make it atleast a bit decent. If they did that, I'm sure that most people would be happy even if it wasn't as well made as the season 1's story.
But no, it looks like they're now just trying to find easy ways of making money instead of actually trying to create something good that would be worth remembering. This had so much potential after the first season and they just decided to abandon it all?? The problem seems to be that kadokawa or the people in charge don't realize why the first season was so succesful, it wasn't about the animation or visual quality, it was so succesful because the story actually had a hidden meaning behind it, it tried to tell you something more than just "some funny animals and human fight cerulean".. The simple explanation of the S1 story is that more than "a funny story about animals and human" it was an allegory of a "perfect society", i.e. each episode was about doing or solving something that in return helped someone, and then in the last episode everyone they helped came in return to help them. There's more to it when I think about it, though this is enough as a simplified explanation. Even if you didn't realize this when you watched it, it was one of the reasons why it was appealing to so many people.
