Its an interesting experience, especially if you have your sound jacked way up. It has a lot of classical music, and some pink-floyd like sounds. However, scenes are very long and drawn out, without much dialog and action. For instance, there is a 3 minute scene of someone in a spacesuit maneuvering toward an antenna.
I enjoyed it very much though, but as sayo said. Once every decade is enough
