I only started watching this last year, know nothing at all about dance, and find it so frustrating that we don't see the whole body - Len talking about heel leads and half the time we haven't seen the dancers' feet at all, so how will I ever find out what they're talking about?
That's one reason why I enjoy ITT but we need to see the feet in the performances above all!
I could understand the camera zooming in to capture expression at times, or "armography" because they are also important but dry ice to obscure the feet is just perversely counterproductive.
