Like Lisa, I guess I can see both sides of the argument. Usually I would agree with Len, as I don't much like the use of props either. But in this case I'm right on Camilla's side. The cape was an integral part of the story and it was fairly obvious what story was being told (i.e. she takes the place of the cape) and I thought they did it excellently. In fact I really loved it and thought it was the most enjoyable dance of the night by a long way. The storytelling in the choreography and the acting was superb - and the dancing wasn't bad, either!
Sometimes Len needs to stop being so dogmatic and start opening his mind a little.
