It is the most patient film I have ever seen!
Very deliberate, which makes the viewer have to use his imagination rather than have others tell her how to feel, think, etc.
I kept waiting for the dialogue, acting, scenery, whatever, to create my next feeling or thought and then I realized that I was doing so on my own. That was remarkable.
The mystery of the hitchhiker and his dog still bewitches me. So many meanings that all seem right.
The driver; he is all of us at one time or another.
I recommend this short to everyone.
