Firstly, I actually enjoyed watching this. This second "season" of Overlord, is rather interesting. Getting to know Supreme One's subordinates and seeing the adventures of the 'unseen' people and beings is quite interesting. There isn't much to say, but watching it was hooking just waiting for the next episode when it was airing, and since it finished airing, I would recommend you watching this just to kind-of find out the details and understand more about Sebas and the others, including some abilities of the NPCs themselves. I'm pretty sure this second season isn't really important towards the season 3, but you will most likely have gaps in knowledge if you skip this.
Art is good as always, I really loved how this season was focused on fighting rather than political issues or didn't provide much fear of a new enemy coming up or such. It was more focused around humans and the interaction with them, especially on Sebas part. It felt as if all of the members from the Tomb of Nazarick were doing their job and trying to gather the information, and instead of it being clipped out as it always is while everything is focused on Ainz, we actually see all of the behind-the-scenes action! It's really amazing to be honest!
Character, actually, was a whole different thing for me. Despite Sebas and the others being just beings that were created by the players and were put into boundaries to behave and act as the Supreme Beings wanted, it feels as they've grown in mind themselves, especially after what Ainz ordered them to change in their behavior.
All in all, this isn't your typical plot-focused season, but more of a introduction before the main story which is going to take place, most likely, in the s3, thus I recommend you watching this JUST for the SATISFACTION during the fights, and how interesting it is to see Ainz find out what's going on, how others behave and what they face. It is thrilling to see the next thing coming up and in fact, this is the first time I've actually weren't able to think or predict of what is going to happen next! Can't wait for the next season!
