The title is 'Strictly Come Dancing' and the winner should be the best dancer. I am not aware that it states anywhere the prize should go to most improved dancer. Dancers with previous training rarely win, but there are a few contestants who deny they have ever received dance training (Tom Chamberlain, the man who won last year and was previously performing dance routines on the West End stage; Denise van Outen who said she trained as a singer, not a dancer, and all those who passed through stage school apparently without ever having had a dance lesson.)
I am sorry Charles was voted out; he was developing and has far more potential than Joe Sugg, who has reached his limit. Stacey's dance was a mess; costume, choreography and her performance, most of which seemed to comprise being manhandled into a series of lifts and a few pas des waltzes.
The advantages the trained dancers do have is stamina which is increasingly apparent; energy isn't enough.
I have enjoyed this year's show so much because there have been some excellent dancers and that is what I love to watch: Ashley, Faye and Danny Jon-Jules, who should still be in the competition; Lauren should have gone weeks ago, and AJ knows it.
