(Jumping the shark is an idiom created by Jon Heim that is used to describe the moment in the evolution of a television show when it begins a decline in quality that is beyond recovery. The phrase is also used to refer to a particular scene, episode, or aspect of a show in which the writers use some type of "gimmick" in a desperate attempt to keep viewers' interest...Wikipedia has a more elaborate explanation.)
The show is getting more and more ridiculous.
I think Uttaran jumped the shark when Veer lost his memory...,
or when the Thakur and Bharati family moved in together.
when Mukta agreed to marry Tej.
or when Taps suddenly reappeared to marry Tej
I guess the list is endless...
