If someone tries to apply the things he/she watches in TV, then that is his/her own dec, nothign to do with the show.. Every show or film has a declaration part at the very beginning, that these are purely fictional stories, and has no resemblance with anything/anyone..
So if after that, someone applies them in his/her personal life, then the responsibility is of individuals..
So for me, no impact !
But, sometimes if one sees very rude stuff or something very painful, it rather helps one to realize his own mistake if he had ever done that.. which is why shows like Balika Badhu, films like Baghban are made.. throughout the movie, they show tortures, but at the end, everything is well with the good persons.. Bandini is not ended yet, and m sure by the end of the show, all nice people will win it ! 😉
Hence, positive impact.. !
So I voted for nothing !
