Judges need to quit rhapsodize get over every performance and contestant. They should be providing help, tips rather than saying "you killed it,, you are owning your talent" etc..
Also, they clearly show their bias, who they want to win and that should go away.
Lastly, they need to learn what to do with their save which would not be to save a Barbie Doll over the best talent they have had in years.
