Much as I find Badi Maa a little too much for my poor ears, I think she is supposed to a hysterical somewhat so I get the characterization. What really impresses me is that balance they have brought in with a character like Bade Papa. He is not too good, unrealistically so, he is just sensible and he has a good heart. He did make a mistake in judging ABir and he was gracious enough to not just admit that but admit it in public.
If there are characters like Kaushal, who is shown as a scaredy cat afraid to go up against Meenu Behnamd also as someone who is incompetent for most part, and Nanu who knows what's right yet relies mostly on Abir to speak up and does not ALWAYS do that himself, there are characters like Bade Papa who politely, calmly stand up for the daughter at eveyr juncture.
Thing I love bst about this show is that apart from central characters (that is, ML/ FL) there are others like BP who are such a positive addition and who are USED to convey positive messages too.
