This movie isn't much of a movie, but a work of art. There is little plot.
The special effects were almost as good as star wars, and the movie was from 1968! They had very high definition film with vibrant colors. Jimi hendrix hadn't played woodstock yet, the moon landing was another year away.
The movie is very slow and at times boring, but when it was released it was a marvel. They had rotating sets as large as a ferris wheel and the ship was a huge model.
I would recommend it to those who have an interest in the past.
