Judges are there to comment on the choreography. It is their job. It is also their job to comment on the presence or lack of emotion and passion on the part of the dancers. However, there is a huge difference between constructive criticism and berating. Just as there is a difference in trying to quantify the correct number of teeth shown when smiling. It is my, and apparently quite a few other's, opinion that Mia crossed the line with Kherington. That is OUR job. We, after all, are the ultimate judges of what is right and wrong when it comes to reality/contest television show judges. Without the viewer's support, Mia will be judging from the comfort of her own living room before you know it. She would be wise to tone down her attitude.
