I like its modesty. Technically not a great movie, but superficial stories and qualities aside - we're all surrounded by that 'ultimate' inevitable, mysterious shadow, our brittle egos in fear of death/disappearance desperately affirming that 'i exist i exist i exist', fear, reasons to live, meaning, loss etc. The ending is yes, lame by some standards, but archetypal of natural innocence pressing on. Simple. Nice.
