The storyline is more complexed than S1. The production was great as expected. The chemistry among old and new casts were great. Liu Yu Ning, Bai Yu and Daniel Zhou had done a great job to welcome the new casts. Dilraba was very strong while Zhang Ling He was the fastest learner. I cannot wait for S3 with this crews.
Frankly speaking, I prefer S1 when the casts had worked together to identify the murderer. In S2, the casts spent time suspecting each other's within the group which I like less. However, the group dynamic was great, especially the final ep when they showed their understanding on each one's strength and weakness...and fully accepted it.
Once again, looking forward to the S3.
