Why were people surprised that Pia was eliminated from Idol last night?

PIA YOU ARE NOT TINA TURNER UNLESS YOUR HIPS SWAG AND YOUR HAIR FLIES:Jacob and Durbin were spectacular. Every Idol showed versatility but Pia. You can sing ballads on a cruise ship, a smoky lounge, but a only balladeertype is not going to sell music or a brand in this environment. You have got to be a triple threat. Her personality is the same, her music is the same and she picked the ong time to let her homespun Tina Turner Diva to come out. No hip ion and no hair movement and don't forget the footwork. No wrong choice of music killed her.
