They did a great job of illustrating complexities and how elements come together. I was certainly impressed by how well this video is crafted in to an easy to follow narrative about this kind of work.
Simple enough without sacrificing the right details and well put together.
Excellent documentary, and that was a kick ass movie by the way.
