This was the first Japanese film that I saw that didn't rely on a giant monster to make it an interesting story (there is a giant monster, but it is mainly used as filler). Essentially, the message of this film is about how the people of Earth should learn to cooperate, especially when faced with extinction. We do not need an extreme threat like an onrushing planetoid to learn to cooperate due to the fact that we have such threats as global warming, pollution, crime and hunger that are already eating away at us. Also, I hope one day that an uncut version of this film is released in this country. The message of this film has all but been hacked to pieces by the American distributors of this classic piece of Japanese science fiction.
