Reply To: Space Films that Convey the Unfathomable Enormity of Space and Time
When it comes to the feeling what it means to travel through space I find THE MARTIAN and GRAVITY give a good impression even though they take place in our solar system, one even in earth orbit.
Then there re movies like DARK STAR, ALIEN and SILENT RUNNING which give me a chilling feeling of being lost in space.
To a certain degree THE BLACK HOLE could be counted in as well.
