I think the industry tends to like to think in the narrow sort of mindset of a businessman, and businessman absolutes, and movies really exist in a much grayer region of dreams and stuff like that, and instinct is prized in movies, it's not prized with the businessmen in movies, but movies themselves often reward instinct rather than pie charts.
I think if you have a really big, heavy person, there's a feeling of an invisible puppeteer jerking them around in space. They don't feel like they are moving themselves.
If you move something 10 pounds through space and then stop suddenly, there's a little overshoot. When you transfer weight from one leg to another, there's a certain way that it happens.
