Story
As I said, it was like an OVA. The first half of the season was about Ains taking over the Lizard villages which, for me at least, was quite prolonged. It didn't seem to serve much purpose to the story in overall, but we'll see how that turns out in the third season. The second Arc focuses on Sebas against an underworld organization called the Six Arms. Again, rather than focusing on the overall progression of the story, it focused more on the gap of level between Nazarick's residents and the rest of the villains and heroes in the world. The reason I found this season to have some value to it are the last two episodes which finally add some progress to the story we left in the first season.
It's really hard not to describe the first 11 episodes as pointless as it stands right now. Maybe if you've read they'd have some value to them, but as it stands right now with no third season yet, they don't seem to serve any purpose.
The first season was all about exploring the world and knowing the people who dwell it and potential dangerous enemies whom may pose a threat against Nazarick which is to be expected since that world differs greatly from the one Ains is used to. Here in the second season, instead of seeing something interesting that might add some thrill to the series, we're shown
Ains playing the cool Overlord guy.
Foes who are basically one shot kills that there was no point in even naming them.
Extremely uninteresting combat. Even between characters who're close to each other in level, they just spend 15 minutes having a little intimidating chat and 5 shouting the names of their spells; giving the actual combat a few seconds of time.
However, this changes in the last two episodes which I'm not going to describe since that'd be like spoiling the entire season's worth. However, you can expect the story to pick up where it left from there.
Art
Didn't improve much over the first season which was indeed good in its art style. If anything, it held up to the last season's standard in art style which makes it somewhat nostalgic and original. The art is a major focus of this series and this season is a proof of that since Ains wouldn't have been able to showcase his abilities and dark aura without good art.
Sound
The first season had one of my favorite OSTs which makes it difficult to compare it to the generic OST of this season. It pales greatly in comparison to the first season that it's not even a competition. Yet, it wasn't bad in general if you don't hold that high of expectations out of it.
Entertainment
In short, if you're longing for Ains' demagoguery then you won't be disappointed with this season as long as you don't mind the story being put to delay until the last two episodes. One thing I personally liked in this season is the use of more bloody deaths in comparison to the first season and I hope they do add even more in the future.
As of the time this review has been written, the third season for Overlord has already been announced for July 2018. Though, this does emphasize my theory that this whole season was a bunch of OVAs they decided to show us to quench the thirst for a sequel. I can't deny I'm quite excited to see what the third season has to offer.
