The Film's Message: Never Arrive! (*Spoilers, BTW*)
I love this film so much, and the ending is one of my favourites ever. I got irritated, though, when reading various reviews that mentioned criticized the lack of resolution at the end and claimed the film was too bleak. Talk about missing the point!
Chiyoko dies never having found the Man with the Key and it looks as though the film's message is 'at last, she will find her lover in Heaven and her life will be complete.' But it isn't anything so cheesy! Instead, Chiyoko, in her spaceship, announces "It's the chasing that I really love!" and hurtles off into infinity and beyond.
Dreaming of a future lover is more fun than actually winning their love. Playing a game is more fun than winning. Researching an essay is more fun than handing it in. Seeking the meaning of life is more fun than finding it.
Go Chiyoko! Keep dreaming and chasing! But never, never arrive!!
