Completely agree that Taylor was great. And exciting on stage. Love the way he moves. It's all his own and he adds to the song and excitement when he does these improvised moves. Katherine is boring. And I don't think she should sing Whitney Houston because she is not Whitney Houston vocally. Katherine cannot "push" her voice the way Whitney ... and Taylor can. She sounds like she's caught in a garage door opener when she tries. She downright stunk when she tried to sing Christine Aguilera and Whitney songs.
I do think Katherine has a great voice though. I just don't think she's found her style. Therefore, she's trying things not right for her. That reminds me of Paris in a way. Once Paris gets her style down, she will be absolutely great.
Taylor deserved to win. He really turned it on and out. He was super exciting to watch and listen to. And if you notice in his duet with Toni Braxton, he held his own. He looked like he belonged on stage with her whereas with Elliot (who I love and wish had been in the finals), he seemed completely swallowed up and overwhelmed by Mary J. She completely dominated the stage. It really wasn't a duet of equals.
America got it right.
