I really like the concept of the show and the opportunity they are giving not only to the artists but to fans and the whole world to know talented people giving everything to make their dreams to happen.
They have an incredible cast, the judges are very objective but at the same time humble and emotional. Lee Seung Gi as good as always being a Master MC and the interaction among all the judges is worth to watch.
The cheers of the contestants to other groups makes the ambience joyful and easy. I can see they are supportive and not as competitive as other survival shows.
