This is my pick. I wish the rest of the movies had the same feel. The set design was the best and told it's own story. Aliens was a disappointment for me. I wanted them to explore the lore more.

Watching the original Alien in a theatre with a group of friends, almost none of whom had any idea what was coming, is one of those indelible experiences of my youth.

So is lining up to see the original Star Wars (The Last Hope) after having been impressed by the trailer that was shown before ‘Robin and Marion’ the previous November. I never would have imagined after seeing it that the franchise would eventually evolve to be dystopian.

One great 70s science fiction movie that I only got to see later on television was Silent Running. It deserves more attention.
