I happened to watch this as it was available on Vodafone play and I think it's a really well made but underrated series. Also one which many haven't seen or even heard of. First of all, performances are brilliant except maybe a few but most of the major characters are excellent. Direction seems to be great as well as the camerawork. Probably the only thing which doesn't work in its favour is the fact that there is a very clear absence of logic in the case investigation. Nobody even goes through basic call records and cell location checks. So many people are killed and there are no eye witnesses who saw the deceased with the perpetrator. This is as naive as it can get, esp when the police/CBI is actually keen to crack the case. If they were uninterested, it could have still made sense. Clearly this suffers from a flawed writing. However if you are willing to ignore the flawed investigation logic, it's a definitely good watch and does keep you engrossed. I rate it 7.
