I finished Overlord II on my lunch break at the office today because I was THAT excited to see the season finale. In fact, I’m actually writing this review at work right now. It wasn’t always this way, though. I was actually a little concerned after watching the first couple of episodes back in January.
Overlord II is primarily a world-building season. That's great if you like seeing minor characters get significant screen time. Not so much if you're a fan of one of the previously establish characters that becomes less relevant because of it. While hesitant at first, I’m now convinced this was the right approach to take. The story is written in such a way that by the season finale I found myself actually caring about many of the “extras” despite their overall weakness relative to the main cast.
Aside from a few ugly bits of CGI, the quality of animation is on par with what we've come to expect from Madhouse. If you liked the first season, there’s no reason you shouldn’t at least give Overlord II a try. I mean, Madhouse did.
