I loved the 4 chairs. Great idea even though the order of the singers was predictable. Looks like Demi is following suit and putting everyone in a chair knowing full well they will be replaced by the better singers at the end of the line. Simon won't do this, just watch.
I thought the black woman's look was hopelessly dated. Dianna Ross would have worn that in the 70s. If they make her style current, she could win this. Her choice of songs may date her, as well. Time will tell on that one. She sure is good and a real beauty!
I also liked the plumber; he has star quality. Kelly's other man does not. The woman who made an excuse (taking meds) was not liked by the audience for that, big time. She may have shot herself in the foot.
