There is no comparison between the mistakes of Sai and Virat.
Virat the character is bashed rightfully because everything he has done has been completely stupid. Yet forum members did call out the inappropriateness of showing Sam manhandle V and Chavannis mudslinging Shruti even though she was despicable, dishonest and not brave enough to speak up despite pleading guilty so much. Ashwini's slap was not called out by many because Virats ridiculous behavior needed some reaction. How is a mother to react seeing her son listed as father to random kid in a birth certificate?! And somehow a mother slapping doesn't seem as bad as Sam holding collar etc. Virat had umpteen chances to speak up, clarify but he didn't use it. Today he is critically ill and thats unfortunate but its ridiculous to compare Sai and Virat.
Devi has been unbearable for a while now. Her superstitions and her daura's are cringe. Even when she blamed V in Sai's accident , her behavior was called put as annoying. She just screeches some nonsense.
Pullu, Mohit and Sam are very on/off. Somedays they get decent dialogues and perform well. Otherdays they are non existent or showpieces. Underutilized characters. But they do an okayish job with the material provided.
And the only reason NB is called out is because his acting is utterly subpar recently.
If he upped his game and got back to doing a good job he will be praised like he has been before.
I would have no qualms praising a good performance by him if he delivered it.
