This show has a lot going against it imo.
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.
