I know Sanjay Bhansali's dance competance has been in question. Well from what I know, from inside sources in the film industry, and from other sources, he grew up dancing and entertaining. In fact, the reason why he and Farah had had a tiff a long time ago was because of the choreography in 1942 A love story.. he contributed as much as she did, but she got all the credit for it, he being her assistant or somehting. I don't remember the whole story, but i know this for a fact. Which is why, in every movie of his, the dances are so visually appealing, because he captures the "essence" of the dance.
