I mean, Christina was a bitch last night, there's no denying it. However, she was right in her critique. Tony is one dimensional, he doesn't vary it up, and he struggles when he tries to push himself vocally (I get the feeling he's become too comfortable with his talent). I'm especially put off by the fact that he seems to think that because he's been around the industry for some time, this sort of criticism doesn't apply to him. He seems to have forgotten that he didn't rise to superstardom like JT, Brit, and XTina. There's a reason why he hasn't made it big.
I have a feeling that America will see through him as time goes on. His celebrity-fueled Twitter follower count aside, his stage presence is forced (why was he being so rough with the audience interaction? lol) and off the stage he just comes across as falsely entitled.
