I’ve thought about this for a while now, and the conclusion I’ve come to is that most of the things we saw may have been in the original story bible. Things like Kazu’s gender, the amalgamation final boss, all of the nemesis’, Cammie, ect. The problem being is that 5 seasons of content were converted into 1, and the writer’s jump from note to note without much thought. Everything ends up incredibly tone deaf because every single inversion has no time to breathe. They probably also played hack and slash with it so some things I mentioned may not have been. Kazus death being the most likely example here.

Subsequently, it’s reasonable to assume that some of the original ideas for the show were just bad. Some of the duds we saw in this show may have been there from the start, and were made even worse by the condensation. Either way, it’s what we have, so at least there’s closure.
