I adore the "wonder triplets", so I was glad to see Derek/Brooke take the well deserved title. This show is "Dancing" with the stars, hence the show is about dancing. Brooke was the most talented dancer of the remaining 3, and due to her natural talent Derek was able to have more difficult moves throughout all of their dances. Things he could never have done with Jenny or Shannon.
While I love Warren, the content in his dances was subpar in contrast to Brooke's. Warren is a great entertainer, but he is not a good dancer. I thought Lance deserved second place, but his freestyle lost it for them, IMHO.
I will miss Julianne, but hopefully Derek and Mark will be back. I think Derek is a major goofball, and I don't see him as smug or conceited at all. He's more like the class clown mugging for the camera.
What I wish is that they could dump Samantha next season and get a decent co-host in like Drew, who actually asked logical questions of the dancers when they came off the dance floor.
