I've been watch overlord season 1, it was quiet fun. But i stopped watch half way through season too because it became one of the most boring pieces of shit ive seen. I'm gonna give season 3 a new try. Is the manga any different, because the way HechtHeftig describes it, it sounds the same.
Well I don‘t know how far the anime got. The adventurer arc wasn’t that great tbh (the first thing he does) but it was good to establish the MC. the lizard arc was great. The way those lizards were drawn, with such a human emotion... it simply shows how even lizards are more human than humans. The same goes for the vampire arc or at least that battle at the end. It was rather a small arc and imo good as well. After that comes the world-building arc that focuses around the butler and a criminal human organization. And this is the last one and imo the worst, since there is just too much talking. And the MC isn‘t shown anywhere. I want to see the MC in action, and not wait for months for something to happen (which is so obvious and bound to happen anyway).
