Well most of the serials on Indian television are of sadistic or or misogynistic nature.
The other day I was watching one of SP shows where the old lady of the house wants to harm her daughter-in-law. Hence mixes glass pieces in turmeric paste and puts thorns in our garland.
Some of these shows are so dark and grim. They would put shows like Saavdhan India and Crime Petrol to show.
Coming to the show,, Shanti when she brought a daughter-in -law to the house. She not bring her home as a daughter but as a daughter in law. This show wants to depict that a daughter cannot never be given the status of a daughter.
