I watched this whwn I was a lot younger, probably too young, and although I enjoyed it I didn't quite know what to make of it. God I am glad I bought it on BluRay. For a movie made before man went into space and had no real clue what it was like, this is a vision. Beautiful visuals and sound even though it was made a year before I was even born. I now get it. It is open to your interpretation but it was quite profound when I watched it again. For older, wiser minds I think. An amazing BluRay.
