Abuse has not been invented to describe this..

Rating: 1/10 (21 February 2020)

The first dialog is about 25 minutes in. Sequences of movement of objects & people in space are several minutes long. I failed to find any profundity in them.
If the visual effects were considered amazing in 1968, well its 2020 and they are hardly above average. Besides any "good" movie with great visuals had a lot more going for it.
The end is just absurd. And makes the almost two and a half hour torture totally pointless.
People who find philosophy in this movie maybe other filmmakers which I understand. But for humans there's nothing in it. Nothing.
