I was initially rooting for Apoorva-Shilpa, but surprisingly as I watched the performances of the first two weeks, I gradually found myself liking the Varun-Rajeshwari couple best.
Rajeshwari is a terrific dancer and moves very well - so she scores over Shilpa. And Varun, though on the heavier side, emotes superbly, both in the first week's Bunty aur Babli number as well as yesterday's song. I also found their chemistry far better than any other couple.
Also, apart from the overrated Sachin-Supriya, it was Varun-Rajeshwari which got the max marks consistently in both weeks. In the 1st week, they got the third highest marks after Sachin-Supriya and Archana-Parmeet. And yesterday, they came 2nd, while Archana-Parmeet got a very poor score of 16.
Of course, it will all depend on what the junta says - as far as this forum is concerned, it looks like the Apoorva-Shilpa jodi is the favorite, so ppl may vote for them regardless of performance or chemistry (like it was for Qazi in Fame Gurukul)!
