You probably don't understand them because some of them probably don't know English so well, and they probably are using google to communicate with you. I am East European but I have a different opinion.
When I first heard that Prats is being replaced I was devastated. I googled Toral and I didn't like her at all. Then I looked her up on youtube and found an old series she played in and I thought "she doesn't look so bad", and at her first pictures as Anandi she looked even better, and I really liked her in the episode broadcasted yesterday.People probably are not used to changing an actor or actress for a role, I have been faced with it multiple times. Things like this happen everywhere, in American, British, Turkish and Indian series, you just have to learn to accept it.
