So I'm about to watch John Carpenter's "The Thing" and I've realized some of my favorite movies fall into this sort of feel. They're sort of dark (they don't have to be), take a long time to build up and convey a lot with very little action. I'm talking about movies like "Alien", "Blade Runner", "2001" etc. While these movies could technically fit into different genres, they all give the same sort of feeling when I watch them.
Anyway I was wondering if you guys had some suggestions for other movies I should watch that could be grouped with the ones I mentioned above. They just don't make sci-fi like they used to.
Event Horizon, sort of. Into the Mouth of Madness as well (though Alien and Blade Runner set the bar pretty high).
