That unique style of dialog tells you right away that this 34 minute animated treat is an "existential" short subject from the BBC, and quite mesmerizing. The first task of the reviewer is to categorize the film to assist potential viewers, but I am coming up blank. In my over 2000 reviews here, I have never encountered a single story that sets out to deliver so much ... and succeeds. It is an adventure, it is a drama, it is a fable, it is animation for kids, it is animation for adults, and it is also a morality tale. It is an unforgettable half hour. Recommended.
