Recommend a good SCI-FI movie [now with public IMDB watchlist]

Pandorum http://www.imdb.com/title/tt1188729/
Dark City http://www.imdb.com/title/tt0118929/?ref_=fn_al_tt_1

I just re-watched Escape From New York last night, it's on Netflix.

None mentioned Event Horizon yet? Weird

-Moon
-Fahrenheit 451
-Los cronocrimenes
-Ex Machina

• The Man From Earth
• Coherence
• Moon
• Ghost in the Shell

• Paprika (the original Inception, and the best one)
• Hitchhikers Guide to the Galaxy (criminally underrated)
• Akira
• Arrival.
• Snowpiercer

Total Recall

You can watch "Alien Covenant" at the movie theater right now.

Hey, psst, "Firefly". Space+cowboyish chracters, shake, not stir, perfect combo.
Maybe some "Hitchhiker's guide to galaxy" for fun time? Brilliant (the book(series actually) is better though).
"Moon" (2009 movie) for some serious mood?
You'll probably like "Dark city". Some of the scenes might look familiar because they were used in matrix afterwards.
Speaking of Matrix, you'll probably like "Nirvana".
The last one I can think of is cyberpunk (still sci-fi right?) movie "Johnny mnemonic".
Bonus if you're into anime and cyberpunk "Ghost in the shell", don't know if movie is any good, but anime was for sure.

District 9 :) Absolutely love it!

Snowpiercer
Gamer
Event Horizon

I'ma stop here... I could just keep making this list bigger and bigger and bigger.
I hope at least one of these movies fit your criteria of "pure scifi" it's a rather hard description to roll on.

Ghost in the shell * is decent but original Anime version from 1955 was masterpiece :)]
But if we start S-F Anime :)

Starship Troopers
Starship Troopers 2
Starship Troopers 3

Prometheus

I'm assuming you must have seen The Terminator, but someone mentioned the sequel and you don't want to skip the first one. Also, all the recommendations for Arrival remind me that the 1996 film The Arrival is worth watching. You should also watch the 1978 version of Invasion of the Body Snatchers and the 1982 version of The Thing.

Arrival was good.

Ghost in the Shell from 1995 is a masterpiece.

District 9 was a cool and well-executed political metaphor.

EDIT: Oh, and yeah, I back the recommendation for Hitchiker's Guide to the Galaxy. It's a great sci-fi comedy; kind of one-of-a-kind. Great humour.

The Quiet Earth (scared me so much as a kid. Far better than "I am Legend")
Arrival
The Martian
The Man from Earth
Gattaca
Contact
Sunshine (the one from 2007)

Okay, you look like you like sci-fi concepts and atmosphere. So here are a few selections I think you may like, that seem to fit the caliber of what you state you already like. Trying to avoid anything too pop-culture insane sci-fi, you seem to prefer more cerebral interesting idea sci-fi stuff.

Must Sees (great concepts and executions):

• Gattaca (I think my #1 pick for you, based on what you already like)
• Starship Troopers (only the first one)
• Fifth Element
• Dark City (very Matrixy)
• Johnny Mnemonic (even more Matrixy)
• Blade Runner
• Akira
• Watch Star Trek in general. I prefer Next Generation / DS9 over the others myself. Original is decent. Voyager can be good in places too. Movies can be hit or miss.
• Close Encounters of the Third Kind
• Donnie Darko. It's odd, but stick with it. "Love it" or "hate it" kind of movie
• Enemy Mine. Absolute masterpiece, but get's overlooked a lot as "Sci-Fi", but fantastic really.

Decent Picks, you may well enjoy, or might not:

• District 9
• Moon
• Minority Report
• Hackers
• Logan's Run
• Bubblegum Crisis / Bubblegum Crash. anime OAV, dystopian cyberpunk with some Super hero overtones.
• Giant Robo. anime OAV. Very nostalgia/classic anime look. Heavy politics and mature themes. Less about robots, and more about humanity and themes around free clean energy for humanity, and the pitfalls it may cause.
• Patlabor 1 & 2. Another anime. Great sci-fi and concepts. More about politics and direction of humanity conceptually.
• Galaxy Quest. An absolute must if you have ANY affection for Star Trek at all, in any form.
• Artificial Intelligence: AI
• Fight Club. Not sci-fi at all, but heavy conceptual movie. Seems along the lines of idea exploration that the movies you cite seem to give.
• Westworld (HBO TV). Quite interesting as Sci-Fi, not really a cowboy show really...
• The Martian
• The Lawnmower Man. Seen it stated earlier by someone else, but be sure to check out the "Director's Cut" version, it's longer and fills in a lot more sci-fi interesting stuff to the story. The DC version i think turns the movie into a proper sci-fi movie, rather than a thriller with sci-fi overtones.
• The Day The Earth Stood Still. Still a classic
• Looper
• 12 Monkeys
• Abyss. Pretend the water/ocean is actually space and this as sci-fi as it gets.
• Equilibrium. Action heavy with gun play, but also heavy concept dystopian future.
• Groundhog Day. Not strictly sci-fi, but great concept classic. Time loopy interesting theme.
• Powder. In more current time and on our planet, but takes on themes of evolution and human/mental potential stuff. Really good movie, fits for the kind of movies you state (high concept explorations).

Some more TV type picks:

• Battlestar Galactica (Newer remake). Treat the first 2 hours as a stand alone movie, it was built that way. Use that to decide if you want to watch the rest of the series.
• Firefly. Great characters.
• Dune (The Sci-Fi Mini-series, not the original movie)
• Fringe. Brilliant series, blows X-Files out of the water in my opinion. While X-Files teases, Fringe is a veritable orgy of Sci-Fi ideas embraced whole heartidly
• Black Mirror

As far as sports motivational movies goes, if you have not seen "Rudy", you may as well murder yourself. That is my favorite sports motivational epic. :p

Serial Experiments Lain, if you don't mind anime.

Have you seen The Book of Eli? It's not an amazing movie but I really enjoyed it

Edit: Also, watch Under The Skin if you're into weird scifi
Edit 2: how has no one mentioned Mr. Nobody yet?
Edit 3: does Donnie Darko count as scifi?
Edit 4: Stranger Things and Midnight Special are both really great homages to 80's scifi
I think I'm done now
Edit 5: Nevermind, I don't think Her and A Scanner Darkly have been mentioned yet
Edit 6: Last one, I promise, but please watch Eternal Sunshine of the Spotless Mind, it's one of my favorite movies
