Anupriya- you need to understand that the very fact that the show is getting high ratings but not the stars shows that these are extremely talented actors that have assumed their roles so well that people are identifying with the show and not with "their personal" persona. That is the greatest compliment to be paid to any actor when we remember him/ her as the role they played and not who they are.
All this adulation and pumping up the ranks are nothing but "flavor of the month"- it is the nature of the world to want change all the time. Gurmeet was top of the charts because he was Raam and later that other character in another serial. Now ASR rules as does the other girl- dont know their names.
