I didn't liked this program because to my thinking it should have been more understandable and knowledgeable for the guests, any how not a big thing.
But I do not see any thing wrong as morally to be said, this dance is a very light thing and to express some friendship with the guests.
I think we should not go so stupidly against every thing and any thing.
Any one criticizing this program because of this dance , please have a look on any video of any of you family wedding / mehndi etc.etc and compare that dance with this, sure it will open eyes.
