I think there's a good chance that Allison will take the whole thing. She has it all, IMO.
I had high hopes for Jasmine, she's so cute but she was horrible. The tattoo baby doll dress girl is gorgeous and I like her voice, but that is such a boring song and she wasn't very good. Cute dress and dance though.
About Adam... I actually think he is great. Cheesy as hell, but he can sing and the girls will love him. I would love to hear a duet between Adam and Allison. They would be such a cute pop/rock couple. I do agree with you, chary, that he is kind of phony.
I also have to admit that I love Nick/Norman and am sure we will see him again in something else, maybe even a wild card.
I'm not sure about Kris. Sometimes I think that we can't hear what they hear and I didn't think he was that good, but maybe it didn't translate well over the air.
