Toral just isn't actress for character of Anandi. And, Pratyusha is 'guilty' because of that. She created character of Anandi (during a years) to be warm, gentle, honest person full of compassion and love for all. And her physical appearance absolutely fulfilled this story. We can talk that any good actor can act out everything. In this case, it hasn't been shown. Each person is a story for itself and so directors and screenwriters choose the right actor according to his sensibility to present a certain role. This series has lost its direction and point and that can see even those who are still watching it. Some of them have their reasons to watch the series, for example, enjoy the view looking at Siddhart, Shashank...or they are great fans of Toral, or they work for creators of the series...
There's a million reasons, but the truth is only one-nothing is the same without Pratyusha. Whether you like it or not. From many attempts to force the audience to accept a new actress, the whole story has lost direction. They can still attempt to bring back Pratyusha and continue the story with her just where they stopped on march 4. If I were in theirs shoes I would ask her to come back. The show like Balika Vadhu would never been so popular and so loved if there weren't this choice of actors and Pratyusha playing Anandi was the core of the story.
I completely agree with you, especially the bold&blue ones, you wrote it so nicely 👏👏👏
