Personally I don't think the CV's or the Channel care how viewers react to a character as long as their TRP's are good.
Besides with the kind of varied members, you would need an entire research team to make a qualitative analysis on the reactions to each character. With the way the serial is changing even a good research team would find it a challenge.
It is very natural for each viewer to find something good or bad in each character as you have done with Tapasya.
Unfortunately all the lighter fun moments with some of the characters in this serial that happened in the earlier episodes are a thing of the past and have been overtaken by the recent episodes.
Let us see what is in store for us now.
