DID1 is taking it too personally. They need to mature a little bit. If I were the judges, I would feel bad as the contestants should not be fighting amongst each other. Bring your best foot forward, dance to your best and stop there. Why is there a lot of bickering going on? Be a true sportsman, do your best and appreciate others best as well!
P.S - In DID1 Mayuresh and in DID2 all the contestants maintain their dignity. They dont partake in this immature thrash talk, they let all the negative comments slide, best part is they do not respond. At the end of the day, all we need to see is the dance, and not taunts and degrading comments which lower the quality of the show. Appreciate each others dance, and dance well. Let the viewers remember the dance moves and not the negative vibes.
