I've finally been able to decide on the top 5 list.
1. Blade Runner (1982)
2. The Fountain
3. Solaris (2002)
4. No Country for Old Men
5. Master and Commander
Honourable Mentions: Blade Runner 2049, Watchmen, A Beautiful Mind, The Prestige, Star Wars: Rogue One, Jakten (A Danish movie), Eyes Wide Shut, Man of Steel, The Last Samurai.
I generally think very highly of David Fincher and Christopher Nolan, although Nolan has a ridicilous approach to cinema sound (he prefers it to be as loud as possible). I generally really, really like the mix of Science Fiction and Noir. I have a Bachelor's degree in creative writing and that includes script writing, so I know the machinations behind a script. It's not hard for me to see what went down backstage as the movie was being drafted whenever I see a movie several times.
@TheDanishGirl I very recently binged all the Alien Movies, I have to say I think the 1st and the 4th ones are the best. I was pleasantly suprised when I found that Fincher made the 3rd movie, but very disappointed after having watched it. I also think the last installment, from 2017 was pretty good. I don't really like horror, but I like sci fi a lot and I'm unsure if Alien really is horror.... at least, I didn't feel scared
