He wasn't really all that exciting. His performance was boring and, like one of the judges said, a lot of the interesting aspects of a performance come from facial expressions; wearing sunglasses totally cuts that off. Established performers can pull it off because fans are familiar with their personality, but a first performance on the X Factor is the wrong time to try and pull that off. I think that's basically why he went - forgettable performance because there was nothing there to connect with!
