I will start from Farha Khan.
In my opinion, Farha is honest. She always looks for performance and that is why she is here. Meenal is a best singer and deserves in top 3. She knows about sur, music and a versatile singer. As far as singing is concerned, she always gives 100%. But according to Farha, Meenal looks like, she is not enjoying singing. So in gala2, she was not happy with Meenal's performance and she gave her views and then Anu malik and Sonu Nigam got angree and started arguing. Actually if we see, Farha was not wrong. She is not biased because next time she was happy with Meenal. Her favorite was Sagar but when she didn't like his performance, she gave negative comment about his performance and he was out. So in my opinion, she is neutral.
Sonu nigam is neutral too and he always give honest opinion. He always says "In my opinion, Karynaya/Meenal/Amey should be next indion idle". His opinions are unbiased and his different opinion for every contestant helps in voting.
But Anu, He is annoying because most of the time he always has a share for each and every contestant specially for girls. He should give his opinion honestly and whatever i noticed he always try to please each contestant. And when he saw his favorite Amey/Meenal in bottom three then he was angry with Janta. He should try to give his opinion like how much he liked a contestant rather than pleasing every contestant with same kind of shares(poems). He should differentiate clearly each and every contestant's performance to help people in voting like Sonu Nigam do.
Tell me, what are your views?
thanks
