Alien
Has to have been at least 15 years since I've seen this. When I was younger, I'd always get impatient and bored because there wasn't shooting and space marines like Aliens. I still did get impatient through this one, but I did appreciate the slow rollout and the logic used to introduce the alien. A lot of the special effects on the Alien and a few moments with the Ash didn't age well, but it's probably not as bad as it could've been because you see the Alien so little. Pretty GOAT liquid movie, though. Everyone's constantly drenched in sweat, the Alien's stickyness, dripping saliva and acid blood, the milky insides of the robot (that's such a great twist now that I think about it, a movie called "Alien" having a robot in it), that one scene where Brett's letting water leak down on him to build tension.
Something I never really thought about before, I really like how the Alien drags off the bodies without massacring them and you're never really told what happens to them. You can presume what's going on based on how the Alien is born and how future movies show you the Queen and such, but never really see it.
Also kinda miss the grimyness of late '70s/early '80s sci-fi. The modern world has made technology so slick and presentable and Apple and small and convenient, it's a little nostalgic to see submarine boards and picture-tube monitors and an entire room dedicated to housing a basic computer simulator
But ye, some things are better since I'm older now, some things are worse because time and special effects moved on, some things are nostalgic because got-old, and a lot of it was realy wet.
