This is an entertainment market and we are consumers. We have every right to say good or bad things about the product after giving the product a fair analysis. I hope the producers listen to that feedback and look forward to suggestions so that they can improve upon it.
When TMKOC started we loved it because it was so realistic. Credit to the original writer for creating these characters. Daya was absolutely hilarious and was loved by all. Somewhere along the way the success of Jetha-Daya popularity led them to making them larger than than the show. Hence Jethalal became ruder to his educated neighbors and Daya became smarter. Which was obviously not digested and criticism started.
If the show changes its characters it is fine because everything/everyone changes in 7 years. But then you can't make them mahaan because these are your normal everyday characters who are ordinary human beings. No one objected to little fights between society members. But Showing Babuji as Gandhij's avtaar or Daya as know-it-all woman or Tapu sena as the superheros for their age will not work and hence the protest starts. And believe me everyone loves the show and still wants to see good episodes. If they are boring then that also must be communicated.
But the CVS must be ready to listen to viewers's comments and also take some risks too !
