The only reason this film is done this way is because of extreme limitations of equipment and process used for its production. While there is value in the aesthetics brought by such process, it’s easy to see how actual content could have been improved. For example, they talk about flow speed, but can’t render it. All flow segments would be better if relative speed of air streams would be rendered as well.
