The two of us watching Scott's charleston were both incredibly underwhelmed. It seemed to follow a pattern of not a lot happening and then there would be a burst of activity which was sold well but seemed very tentative with half the energy and movement it needed. Seemed ridiculously excessive marking, especially as it leaves the judges no where to go.
Can't comment much on Kara's dance, because Artem has a very strong presence on the dance floor and Kara to me doesn't have any whatsoever. I just never notice her.
