My reviews are after watching both the seasons.
I feel season 1 was quite good and season 2 had the potential to be even better. The ending of the season 2 was ???? Probably why I felt season 2 was not as good as season 1 is due to a number of reasons ( I am listing some of them below ) :-
- Improper plot development.
- Maeda being still alive somehow didn't give power to the plot. In that case they could have shown more involvement of her character. That was lacking.
- Should have ended with a finale in season 2, a possible season 3 would simply mean an overextension.
- Seung-jo should have been the antagonist instead of forming alliances with Tae-Sang, because that was the vibe we were getting from him the whole series. It didn't make sense.
