I am sure these contestents are being told to "act" this way!! Some of them go ahead and do it and some express reservations in carrying out what is told to them......
Yashita from a big city is probably more open to acting and carrying out what producers of the show ask her to do whereas singers like Pratibha are not yet open...
Always keep in mind, these are all stunts to keep (in fact I should say get - because its been all time low) the TRP of this show... Somehow they believe they have to show some "bold" moves (Yashita), "emotional" controversy(Debojeet), "drama" (Sara Raza issue where she said people in Pakistan are against her participating) or "comedy" (again Debojeet's Shayari) or "tension" (Guru drama) to get the viewers...
Also remember the stunts they are pulling through - Jail, Court and now this Mahabharat stuff... .nothing absolutely nothing is going to get them TRP ... unless they go back with good singers, good gurus who talk about music and take this forum to give some knowledge about music to the viewers...
I am sure all of us notice that the program is of 1 hr - but 30 minutes are just for the ads.... The companies who are sponsoring such shows (or giving money to be on this time slot) should also pull off ... its not worth the kind of money they are putting........no one is watching this show and you better use your media budget somewhere else.............
