Total and utter waste of time and patience. At least you can watch the first season in hope for something good to happen next. Alas you will still be waiting for it even after the second season. After watching the 2nd season you will question the writer's & director's intentions. I am so disappointed that don't even know where to start.
Underdeveloped characters, so many loop holes in the main story, actions without any logic or sense, no sense of justice (at least not by the end of season 2), no loyalty or trust at all not even among friends (anyone can betray anyone except for the bad guys who have solid loyalty towards each other)....
& last but not the least "spoiler alert" in the whole story they (the writer, director & producer) wanted to build DSP Ghosh character as a sincere, truth seeker and good police officer who didn't kill anyone in his whole carrier but in the last episode of 2nd season for some twisted reason decided to kill the main character KOYAL upon whom the whole story was based on..(didn't even think to kill the main perpetrators whom she was trying to kill in the last fighting scene). What a bunch load of C**P...
There are mini series which are better then this...go & watch them...Don't waste your valuable time.
