Sorry guys....as well as Naman-Megha danced (and I'm a fan of theirs), it's true that the concept just wasn't evident. It wasn't just supposed to be a contrast of themes. The two individuals of each jodi were supposed to contrast with each other. The judges were absolutely right in saying that there was a problem.
And just because you are Naman-Megha fans doesn't mean you should put down Shaleen-Daljit. The choreographers for Shaleen and Daljeet came up with a very unique concept and the couple carried it out beautifully. Like Farah Khan said, there was something magical about the performance.
And about not being able to see Daljit's expressions...Do you really think they should have abandoned such a beautiful concept for just that reason? The judges have already seen Daljit's expressions...and will see them in future rounds. But this round was about something different for them. It was about not being able to see each other and still dance in sync. It was about conveying a reality vs dream concept and having the audience become absorbed in the elegance and magical qualities of their dance. And they succeeded.
