Krapopolis isn't a bad show at all actually. I'd say it's like a 6.5.
My main problem with the show is how inconsistent the quality is. You'll get good episodes like the forest party one with the wood nymphs, the evil tail, or the hydra episode, and then you'll get subpar ones like the ice week episode or the crown thief one. It's just frustrating because technically season 2 aired with the first so the second season airing right now is actually the third, so you'd think the show would be developed and already solved with the issues in the first season, which to be honest, the first season had some of the show's best episodes. But no it's just too inconsistent to be called a great show and that's the problem.
For characters, Tyrannis is just not very interesting and it's hard to care about him because he's just boring and episodes where he does shine like the evil tail one are all very predictable in the end. The most interesting characters are Stupendous and Hippocampus. They are easily the two best characters in the show and I find myself liking their stories much more than the other three characters. They're interesting, funny, and have some sort of depth to them that the other characters lack. Shlub and Deleria are alright but they're just filler characters for me in all honesty.
Also, this show relies too much on killing for its comedy which gets old after a while. I get it's a show about gods but they should change it up every now and then. All in all definitely not a bad show at all but they need to be more consistent with episode quality, especially since they are in the third season already.
