There were really small flaws but really looked bad during the scenes..there was a period during 1984 in kolkata and they showed everything old style but only the Mini bus which they took was off this era as those days kolkata didnt had those types of buses... there was a chasing scene where Hedua was shown and then Howrah bridge it was not nicely placed same places where shown repeatedly..which was distracting even for the people who r not from kolkata but observe things... all together I didnt like much it was a okay types of series, better series sometimes we would get in other platforms... at the end it was like why did I watched it.. some may like it but this is just my observation.
