Ok - here's my thoughts for the bottom half of A.I. (in this order):
Constantine just did not hit any right notes - yuck! Anthony - ok, what straight guy sings Celine Dion & wears a thumb ring? Vonzell was just too flat in the beginning, I liked her ending, but she didn't start out so well.
I really liked Carrie (she still needs to work on performing a little more), Scott sounded good (although the judges didn't like him, and I still hate Scott's dirty looks he gives when he doesn't like his feedback), Bo was just ok.
