1. The CVs were sensitive and decided showing a rape scene would be too much violence for the Indian TV screen. So not showing the rape scene actually brings out the sensitive side of the CVs to not make the story too bleak and dark
2. The rape of the main female protagonist would have been unacceptable for the general Indian audience. The rape of Anandi would have tarnished her "purity" and would have made her less acceptable among the viewers. So Anandi experiences a near-rape but not a complete rape and thus she still keeps her ""purity" intact. A raped Anandi, like a lot other raped women in our society, would have been seen as someone "impure" and not worthy of playing the main protagonist.
I personally think it is the second reason. Though I feel greatly relieved that Anandi was not raped, when I come to think of how her rape would have probably diminished her acceptability, it makes me shudder to think about the general mentality of the larger audience about rape.
What do you guys think?
