In the first season everything was about Nanno, so the stories were all disconnected from each other. Here there are more elements that tie the stories together, including the Nanno vs Yuri subplot developed all throughout the season.

Chicha shared on social media that the episodes would be dealing with social issues in Thai society and to be honest I could see some social topics being briefly touched upon, such as the respect towards authorities in episodes 5 and 6 (which I interpreted as being related to the protests against Thai monarchy) and wealth inequality in episode 3. This is something I really appreciate, because it gives more depth to the whole show, since the first season also tried to teach some morals.

What I liked the most about this season compared to the first one is how much more horror it got. Right from the first episode, we see how sick things get. Nanno is way more severe in her punishments and I can't say I didn't enjoy this.
The Nanno vs Yuri subplot is a little unnecessary. It gave more flavour to the show, but I don't think much would have changed if it weren't there.

What disappointed me was the ending. Not because Nanno died or because Yuri won, but because Nanno was trying to make a difference in the world, while Yuri was motivated only by hate and anger. Nanno is a sadistic character, but at least her actions serve a purpose, i. e. make the culprit repent (at least in the first season, in this one we don't see this side of her too much). Yuri, on the other hand, is a very dark and negative character, that doesn't care about who is right and who is wrong, she just wants to see people destroyed by their own actions. The final episode was also a bit stupid. The whole thing about mum vs daughter in my eyes didn't justify Yuri's words, according to whom Nanno couldn't be the judge because it was unclear which character was at fault.

If I didn't count the last episode, I would rate this a 9.5, but that episode really let me down.
