I don't hate this season, but I have to admit that it lacks that COOL vibe and seems unnecessarily heavy compared to the previous one.
We've been circling around the same villain since the beginning, and I kind of miss those exciting fights with small evil spirits. Most of the time is spent on fighting, Even though I love that part, the overall story is lacking which is needed to hold us to our seats. Even though the family of counters were established in S1, there's still room to explore and add new areas and directions for each character, after all, that's what any good writer is expected to do. Plus, the new counter is neither exciting nor useful at all and his background or powers don't add much to the story. Also, none of the counters matured much throughout the season. The villains introduced in this season were just plain evil & annoying, they don’t have any reason to be like that which is irritating, in S1 Even the villain had a back story which helped us connect to the drama. Leads aimlessly fighting the SAME evil spirits throughout the drama is boring and is an example of lazy writing.

This season they made "So Moon" as the lead and the rest were supposed to protect him and back him up most of the time??....Season 2 was supposed to proceed on the base laid in Season 1 where every counter was equally important and had their own essential part to play with their unique strengths.....Despite being an avid fan of "So Moon" I love the counters as a whole but unfortunately they were neglected from my pov.

Still, I would recommend watching it as you will enjoy it if you love action dramas but go without the expectations of season 1
