I skipped Overlord when it first aired, but then back in the summer season I started watching it for no particularly strong reason; as I said at the time, it's ridiculous and overpowered in a way that amuses me. At that point I'd watched up through episode 7 and stopped. At the end of the year, in the between-season doldrums, I finished off the rest of Overlord's first season (after being annoyed because it had moved from Crunchyroll to Funimation in their great split, and Funimation is a pit of annoyance).

While I pretty much enjoyed the first season of Overlord as a whole in much the same way as I enjoyed the first seven episodes, I will not be watching any more of it. The short version of why not is that starting with episode 8, Momonga is revealed to be an extremely unpleasant person; he is basically a cruel and casually murderous sociopath. Although none of the incidents involved are significant bits of the story (and they don't happen very often), all of them happen without the story so much as raising an eyebrow. For me, this irreversibly taints the show as a whole, because it is actually following a villain and getting me to cheer for him in his goofy, overpowered antics and so on.

It's to Overlord's credit in a way that it's possible to watch the rest of the show, enjoy the spectacle, and to root for Momonga in it. It's very easy to forget that a few episodes ago, Momonga had some perfectly decent people murdered because they were making his life inconvenient, and I'm relatively confident that in the future, the incidents of murdering and cruel killings and so on will be few and far between. In a way that's why I don't want to watch any more of Overlord; I don't want the feeling of the show persuading me to cheer on someone I know is actually a nasty person.

(And the revelation of Momonga's nature has destroyed my interest in him as a character.)
