It mostly sucks because it´s only composed of 2 actual characters, while the rest are worthless jokes. And those two aren´t even that good. Lunaris is a boring slog and Penumbra is decent.
The problem is that they decided to go for a boring new villain instead of the best villain they already have: Glomgold. He should have been the final boss this season. I get that he´s supposed to be pathetic, but he´s dangerously stupid enough to at least win once.
I don´t know, maybe they´re saving him as a real threat for the series finale.
