Alien (1979)

The entire movie embodies Cassette Futurism, but IMO the self-destruct sequence is particularly great. The entire process looks so satisfying that I probably wouldn't be able to stop myself from running it if I were one of the crew.

This and Bladerunner is on my watchlist.
Yeah, Blade Runner is also amazing at capturing the aesthetic. I watched the final cut version of it, which is the only one that Ridley Scott got complete creative control over. Haven't watched the other cuts but did check out the monologue voiceovers on youtube that are on some of the other cuts, and I didn't care for them. The happy ending on some of them also seemed silly. There's a whole Wikipedia article about the various versions lol.
Haven't yet watched Blade Runner 2049 yet, but I've heard it's worth watching. Not quite as good as the original, but not much worse.
Blade Runner 2049 is a fantastic movie. Maybe not as creative or groundbreaking as the original, but very very well done.
