You know, after watching that film (I was around nine years old), I had a hunger for more space films. But what I received, barring Silent Running, was space westerns. Gun/laserfights. Battles. When what I wanted was more about the great silent mystery of space, the beauty, the immensity.
The only visual that's come close to what I wanted then, is that shot from Guardians of the Galaxy where the Milano enters the giant alien construct in space.
I could watch that scene on repeat for hours. I think we all missed a cue, y'know?
