I say this is a golden opportunity: recast the role with someone new. đ
My suggestion: Sayantani Ghosh.
See it would be fitting too since this way each actress would have played a specific phase of the Goddess. Mouni played Sati, Sonarika played the younger more naive Parvati who went from a "human" (on this show) girl to Mahadev's wife. Sayantani can take her role to the next stage, playing Durga, Kali, etc as well as Parvati as a mother and so on and so forth. Plus she can actually act (and dance!).
So I say out with Sonarika. Enough of the awkward acting. Bring on Sayantani. đđ¤Ł
This post is mostly in jest, though partly motivated by my own critical view of the actresses chosen to play Sati and Parvati on this show. Sayantani would have been a far better choice I believe. Or Sriti Jha (and even Mohit would agree đ) but she's busy with her show.
