The concept is unique, a good thriller to watch. But there are plenty of mistakes in the storyline, which are easily observable and they are made in order to show the villain stronger.
CBI is shown too careless and weak at times. How can the case lead ignore a dog barking at a site where they are searching for a human body? The last episode is too dramatic, Dhananjay reports every vital information to Nikhil who is all alone finding the three hostages without any police support. Sacrificing Riya was unnecessary, the security at their home could have been informed to protect Riya. Rasool isn't questioned as he was the last person with Lolark before his death, he continues his services with the CBI.
Also, lead cast Barun Sobti (as Nikhil) doesn't give justice to the role he has played, his performance is dull, and dialogues are indistinct.
