Poetic in style
In its surreality and brevity there was profound complexity, here is this being trying to make his way to the stars, but he doesn't torture himself over his quest. I feel that this movie seems to inspire a feeling of obsession without insanity. That we can hope to achieve a great deal from our modest lives without ruining ourselves.
Or maybe this guy is already insane as is wandering the void of his shredded mind.
The tranquil tone of this movie seems to point towards a feeling of the self, so I can only assume that this is an introspective journey of this person. That in their own consciousness they feel lost, but they haven't lost their feeling or purpose.
Either way you slice it, this movie is really good. Normally this sort of thing makes me depressed, but it was that smile at the end that saved the movie for me.
