You know, when I first saw him I thought 'This guy doesn't have a chance but I'll give him credit for trying'. Then he started singing and I could not believe that voice was coming from him. I was glad to see him in the following episodes....and shame on me, he lasted till the end. He is one of the most talented people on that show and I"m glad he made it to the top.
There was another guy that surprised me. I don't remember his name but he reminded me of Harry Potter

little dopey looking kid with glasses comes out and again, I thought 'I'll give him credit for trying'. Then he started singing and I couldn't take my eyes off the show. I could not believe that voice was coming out of that little guy.
These are the times that I'm glad I'm wrong
