It's not weak - its silly.
The show started off so well and did well till Kirti came. Even after it was okay but then there was no progress at all. Its like whatever new track they bring, it ends on Kirti ruining it.
It would be better if they just stop it - don't think anyone's interested in how it ends or what happens. Kirti was the worst character they introduced - there is no other side to her at all, its all just revenge revenge revenge and that too - completely baseless. She wants to ruin Leela yet fails to comprehend that her mother and mother's parents were at fault!
I don't think I've watched anything after the garba episode... don't even know what is happening but its probably still about Kirti. The show shoud've been named "Hamari bahu Kirti" instead of "Hamari saas Leela".
