Performance 1: They compare tanaaz to Helen and Bakhtiyar to Shammi Kapoor. Yet do not find anything wrong objectively with their performance and give them just 9. However when it comes to Tina and Hussain, why are they not compared to Madhuri and Prabhu Deva. They even admit that their performance was ok but end up giving them complete score.
Performance 2: The judges admit that Tanaaz and bakhtiyar's performance was so good that it brought tears to their eyes, yet when it came to giving points they gave them scores equivalent to the worst performances (Yash & Ghouri) of the day. i.e. 8
Talking about the judges, only Malaika was anywhere close to judging based on performance. For Kunal Kohli, even if Tina would not have performed, he would have given her 20 out of 10. Yes you read it right. If you have any doubts, watch any of the episodes. As far as Saroj Khan is concerned , she is probably getting a contract in Kunal Kohli's next movie and so he runs her judgement.
