Perhaps I'm biased because have seen Anandi's story for so many years and I love the Anandi-Shiv pair - am so missing meaningful scenes between them 😔 . Also, like you said, different parts of Ganga's story have been done before in BV though they've cranked up the level of abuse Ganga faces. Ouch!
That said, I'm fine with whatever CVs cook up as long as they make AnSh substantial and move their story forward. I anyway watch BV for AnSh, Surekhaji and Bhairon so when there is enough focus on them, I'm happy.
