I think the charm of this whole artifact is loosing it's identity. I was a very big fan of this whole series I would say. Anirban the best part along with the stories and his two friends added a sweet melody to the essence. But from the last 3 season with the change of the character the flavour was somehow dim. But to me it was very sorrowful to watch as from execution,story and all the other charms which this show had had somewhere lost it's path for the time being. I believe myself as one of the very early watcher of this series and also influencing people to watch and hunders of watchers I believe had sleepless night enjoying this, but now with heavy heart I would rest my saying also adding that there are some new watchers who are loving it. But then "old is gold and loyalty is a two way street".
The characters needs to be worked on surely please.
