Great scenes for the 60's, a joke for our time

Rating: 6/10 (6 April 2018)

There are serious problems about this movie... First it's unnecessarily too long. We don't have to watch at least two thirds of the movie to understand that it's about a meaningless evolution of the human race to reach a nonsense level technology. The movie was shot at the age of space hype which justifies the excitement it cause reasonable for that time. However after living all these through we all know that things about the space technology would not develop that fast. We still use small capsules to reach a low orbit space station after 50 years. That's all we could achieve after many accidents and casualties.
Has anyone understood anything about the last part of the movie?
