In all honesty, I think the judges are biased towards Baichung. I like Baichung and have nothing against him, but to penalize another contestant for not lip singing and then letting Baichung off the hook with a 30 regardless of the fact that he does not lip sing is unfair! This is a competition between EVERYONE. They have to have the same standards for every single contestant.
Also, Baichung fell last time and he didn't deserve the high marks he got. I remember once when Parul fell during one of her performances, she got low marks for that.
The standards should be the same for everyone.
