When I first watched this, the rest of the trilogy had not been completed yet, so I viewed this short film just by itself. At first it seems to show the inner life of a rather strange stick-man with whom some of us can relate. Then it goes completely off the rails and shows that he has a serious brain disease that is making his reality completely fall apart. This becomes terrifying and very affecting. I did not know that it would lead to another two great installments but even by itself, this is a truly terrific piece of animation.
