its unfair to target just neerav, even sneha kapoor was in JDJ.Anyways, all the contestants on DID are somewhat professionally involved in dance. Even kruti was a semi professional classical dancer dacing in functions. An amateur would be someone who just learns dance for the fun of it.
But you cannot get into a platform like DID if you do not have connections and experience , it is next to impossible.
I have a friend who is into dancing for a long time and she does stage shows and she is not a professional dancer. she tried for DID and said it is almost impossible to get into the show if u do not have some foothold and connection and experience.
Remember the show DPL? most of the dancers there were dancers and instructors of Shiamak davar's troupe, you can see them in all the show he choreographes or movies he does. Did that stop them from coming and auditioning in DPL or getting selected? and there were a few other amateurs too.
Everyone comes to DID to try their luck, get recognition, learn advanced techniques. and everyone deserves to get a chance.
