I agree! If they wanted repeat performances from past shows, then they can't critique it by saying the former dancers for that routine was better. But I think Nigel actually said that the dancer that did the dance from Twitch's dance was BETTER than Twitch, which shocked me! But you can't erase a routine from your mind that was previously done, and NOT compare it. So for that, it was unfair of the judges to do so.
But as usual, I'm thoroughly enjoying the show! But I do have another critique about the judges. Some of the judges they are getting are so boring! It seems those that are ballet pros have NO pizazz, and add nothing to it. I think they should keep Christina Applegate and the other funny guy.... with the red beard... what's his name again? :)
