Nope, I'm not a big Mark fan.
(1) I think he choreographs, stages and costumes his dances to hide the inadequacies of his stars. Derek, OTOH, choreographs, stages and costumes his dances to show the strengths of his stars.
(2) Mark's shimmy-count.
(3) His dancers tend to be overscored but even then they only make it from week to week on fan votes.
(3a) Case in point:
http://en.wikipedia.org/wiki/Dancing_with_the_Stars_(U.S._season_11) Season 11. Brandy and Maks had a combined score of 57 with a perfect 30 in their tango. Bristol and Mark had a combined score of 53. Brandy went home and Bristol went to the finals.
(3b) Case in point:
http://en.wikipedia.org/wiki/Dancing_with_the_Stars_(U.S._season_18) Season 18. James and Peta had a combined score of 58. Candace and Mark had a combined score of 51. James went home and Candace went to the finals.
I find it ironic that the same forces that sent him to the finals twice sent him home last night.
