Jhalak is a show where the celebrities who 'have never danced before' try their hand out at dancing. So, the standards by themselves are incomparable to DID...where its contestants who have danced all their lives and are passionate about try to win the crown of DID.
Yes, like Dabulls Di said, Jhalak is more about supporting your favorite celebrity, regardless of how they perform, there is no one better than me who can understand that partđ Anyways, yeah, DID is more about picking your favorites on the basis of how well they perform ie your favorites aren't predetermined.
So, I don't think you should even expect the standards of JDJ to be higher than the standards of DID as far as dance is concerned.đ JDJ is more glamorous though.
