i kinda see your point... i too watch so you think you can dance, Dancing with the stars (america) and in terms of dance, they are more authentic and accurate, Latin-ballroom, Salsa, Tango is like classical dances of the West.. but given the material, concept and theme the contestants were given, i think sushant and shampa did outstanding and that as a perfromance, it was a whole package.. thats why they got a perfect score.
Again, we have to lay the blame on the JDJ creative team, that comes up with these concepts.
but adaptation is again subjective and dance is all about interpretation...
authentic latin-ballroom, salsa, tango maybe too sexy for indian audiences.. so toning down is important too..
i remember, in so you think you can dance, there was someone ( i think she/he was white) who did dance on bollywood song.. so when cultures are becoming aware one another latin-ballroom, etc on bollywood songs is bound to happen....
also if was restricted to only bollywood dances then whole thing becomes too boring and repetitve..
so in my opnion, i liked the mixing of bollywood beats to the western style dancing and sushant/shampa were the best in terms of the whole package.....
