I feel the same way. He's really been growing on me since he toned down the gay. He really is amazingly talented, and I get the feeling he's a likeable guy too. I don't feel any arrogance from him, or a sense of entitlement even though he's clearly the front runner. He's only had one performance that I really hated, which was week 2 I think, the sitar thing. But when he did "Mad World" I just melted for him. I hope he doesn't decide he's a shoe-in and bring the drag queen back. Not that I've voted for him, I'm an Allison fan, but he doesn't need my vote.
I agree; Adam seems nice. He is very polite and respectful to the judges.
