I did not watch S1 due to lack of subs so I can't compare. But I loved the whole gang, they had a lot of chemistry, and while some complain that this season was only scaring the actors, I loved it and was laughing my a** off every episode.

I was familiar with Justin but he impressed me here since he was smart and proactive and one of the bravest, being the youngest. He also contributes with the fanservice (as in looks, with glasses, hair, hats, etc).

Da Laoshi is funny and he always has a lot of energy. I am used to him since I am a regular watcher of DDU/TTXS. He makes the funniest faces sometimes, and says some silly things here and there. Love him.

Guo Qilin is a cutie and looks the youngest, with that baby face. He is, along with Deng Lun, one of the scaredy cats. BUT, he is also very smart, there were episodes where the others had a big "?" in their faces while he was explaining the clues. Super cute! Love that the Fan brothers (from Joy of Life) got reunited in the final 2 episodes. His "brother" is also another scaredy cat XD

Yang Mi was my least favorite but I loved her relationship with Deng Lun, how she teases him, it is like a big sister/younger brother thing.

Deng Lun... ahhh one of the reasons I watched this. Not only he is super good-looking (and he knows it... my, does he!) but he is also super charming and even if he was screaming in fear in every episode (he is terrified of the darkness) I was laughing as it was the first time I watch it.. every single episode. He is so funny! He wanted to be the captain so much... he may be smart (this season he couldn't prove it much) but his fears were stronger XD

Loved the group, and loved the final 2 episodes with He-ge, Haoran and Zhang Ruo Yun (from Who is the Murderer)
