concept copying is the worst possible thing in my eyes. its ok if its like for a school dance or something, but cmon these choreographers are sposed to be professionals. this is just not done. what annoyed me most was how all the judges went ga ga over the concept and said its totally fresh and never seen before. the choreographers took credit for somebody else's work essentially.
also, i've read a of ppl saying that movies, songs, etc are copied in india so why not this? i disagree with this 'everybody is doing it so why cant i' attitude.
