I've said it for years. It's not the five point dance floor moves or the swooping Technocrane moves that are your undoing, it's the seemingly easy moves that get you every time. I think it's because it looks so easy that the Director is thinking, "What's the big deal?" while you try to move with an inexperienced actor, that the really big moves (that you make look easy) get buried. I've talked about this phenomenon with steadicam ops and other dolly grips, and it holds true.
