I binged the entire season in two sittings so the episodes blended together for me. Keep that in mind when you read my review.

The pacing of the drama is different from  the first season. Probably because the director changed for season 2. There are quite a few plot holes, some very obvious and some only noticeable after you watch the episode a second time. The pacing feels slower compared to the first season. There was also a serious lack of character development in the protagonist (Fang Mu), or any sign of him showing trauma (or recovering from it) from the first season despite the theme of show being, y'know, about the mind. There's also less profiling of criminals and more old fashioned detective work from our protagonist despite him being a profiler.

The opening case was nice, very nice, set the mood quite well. And then the next episode we didn't see the protagonist until near the end AKA protag's existence feels weakened in this season. Also there were way more cliffhangers than there were, y'know, actual gratifying stuff like finding the criminal, which is a minus for me.

The overall mood of season 2 was not as dark (for me) as season 1. Probably because of the director's lack of experience combined with the fact that he is directing the second season of a show and has to mimic the style of the previous director (to a certain extent). And also because of the antagonists and the emotions they evoke. Not gonna say more cause spoilers.

TBH I prefer the first season more. I rewatched episode 20 of season 1 several times already since I finished it a day before I started season 2. I guess it's because
