Hi,
Agree with your point of the judges. But please note that such things are stage managed to keep the show spirit and make it look real and interesting to make the audience feel that the judges do have different view and they argue over this. Back stage scenes are different.
After all Anu Mullick now shares the same seat with Alisha, who had accused him and dragged him to the press (I think court too) few years back.
All what we see about the judges argument are only to keep the show interesting and full of life and make it the talk of the town.after all audiences would enjoy their arguement.
Do we know that in parallel there are other best singer selection shows on the air in ZEE TV and Star TV also. They are not as that popular as this Indian Idol. It is because that the marketing is less and the Judges are not highly vocal.
Even some shows abroad do use this stunt to get higher viewership. Its all business, nothing personal.
