Watch it if you're okay with unrealistic and totally illogical script.
I don't know how this series got 8+ imdb ratings. There are countless loopholes, by the end it was unbearable.
Forensic team is handling all the cases, murders by the killer is like watching worst episode of CID. Initially it was quite interesting, the mystery of finding the masked killer and suspense they created mixing mythology and real world crime was good. But after 4-5 episode it was like what the heck is happening. Coffin murder scene was like the most disappointing moment for me, how illogical the writers can be. Better watch Crime patrol, you'll find much interesting stories there.
Many of the small small details were so wrong that any crime thriller enthusiast will get frustrated. Hacking the data, finding the gps location of a fitness tracker watch and many numerous things which killed my mood. Many of the people liked it, maybe you'll like it too. But Not recommended for crime thriller enthusiasts.
