A plot that's straight out of a highschool dropout's mushroom-fueld fantasy (complete with the self-insert).
Characters that are based on vague ideas or one-off jokes
Good animation, but a weird lazy-feeling character visual design.
BUT despite that, the show knows exactly what it's doing and so far everything comes together seamlessly. The writing is tight, quick, and funny and there really has not been a missed story beat so far.
Yeah I think based on how stories work there's definitely going to be a pretty major twist. If there's not that would suck but so much of the story is being telegraphed and I think the quality of the writing so far has proven that the show runners probably know that. If it's the same team that brought as scavenger's reign then I have faith right now.
