And that is one piece of good hard SF and a movie that dared to expect something of the viewers instead of force feeding everything.
It did remind me of a lot of other scifi though, it was heavily inspired by older stuff and not just 2001: A Space Oddysey.
I think I recognized bits from Cities in Flight for instance, and Hinterlands by William Gibson.
But this is a movie that will find a place on the shelf next to Moon, Contact and others of the harder kind, to be rewatched multiple times.
