I didnt watch the show that Hard Kaur was on. But based on the video here, Mayuresh-Alisha were 100 times better and had crisp moves and sharp finishes. Amar-Shakti act was awesome and one of the best on DID in both seasons!! I didnt like Hard Kaur one as they look bulky for a Paso Doble act, and her costume didnt seem to be right, and the pair lacked grace too. Both Mayuresh-Alisha and Amar-Shakti carried the acts off with great elegance.
Ok fair enough. I can understand why you didn't like HK's act. Had you watched Jhalak Dikhlaja, you might have liked it. But the thing is that JDJ is a very amateur-ish show and only celebrities can take part in it. HK was one of the best dancers of the show though she was not my favourite and most of her dance involved more lifts and less dance...😆. DID is way ahead of JDJ so I don't expect anything extraordinary from the contestants of JDJ.
So I guess Mayuresh-Alisha and Amar-Shakti can't be compared to Hard Kaur-Savio.
