Though when you say "future", it doesn't have to be a thousand years in the future.
EDIT - And you're discounting a Golden Age movie like "the Day the Earth Stood Still" which is clearly SF, but effectively takes place in the (to them) modern world.
Or its decent cousin The Outer Limits!Not to mention so very many episodes of the original Twilight Zone!
Please stand by...Or its decent cousin The Outer Limits!
Seeing "The Day the Earth Stood Still" mentioned had me go look up a few things. The AFI list for sci-fi (put out in 2008, so not much time for things to make this list) had:"The Best" tend to have real staying power, as opposed to being box office hits. How many science fiction movies to you remember form the 1950s, for example? My mind immediately jumps to 2, then another 2 sort of sneak in the back door when I'm not looking:
"The Day the Earth Stood Still" - Arguably the first anti-nuke movie made in the US. Sure, it has a beautiful girl and a big shiny robot, along with a little action, but it's more about taking a good, long, dispassionate look at ourselves.
"Forbidden Planet" - Another one with action and a big robot, but it's based on Shakespeare's "The Tempest." It covers the nature of man, good and evil, etc..
The others...
"Invasion of the Body Snatchers" - A movie with multiple remakes. Thinly veiled allusions to communism and the Cold War, the nature of being, etc..
"The Thing From Another World" - aka "Invasion of the Carrot Man from Outer Space." A good enough shoot-'em-up SF that it has been remade, twice. More thinly veiled allusion to communism and McCarthyism.
These films are watchedd again and again, debated over, or just plain enjoyed. I don't know that many movies that rely too heavily on special effects, rather than story and character development, will be able to say the same.
I’ve seen 18/25.
I have not yet watched Snowpiercer, Colossal (although I meant to and now again plan to), Attack the Block (same), Under the Skin, Gravity, Edge of Tomorrow, or Interstellar. Both Gravity and Interstellar, specifically, I missed the chance to see in 35mm or another proper prestige format theater and still hope to. Under the Skin was not on my radar at all, but Snarf’s comments in the OP definitely spark my interest.
Since neither Children of Men or Primer fall within the 15 years, I don’t see any egregious missed inclusions. Sunshine, Monsters (2010), and 10 Cloverfield Lane are probably more worthy than (of the ones I’ve seen) Pacific Rim, Rogue One, and Guardians of the Galaxy, much as I enjoyed the latter two. Dredd, the 2011 prequel to The Thing, and at least one of the Planet of the Apes movies are reasonable contenders too. I liked Pandorum as well.
My top five from this list evaluated as sci-fi films are probably Her, Ex Machina, The Martian, Annihilation, and Fury Road. Just as movies the order probably more like Her, Fury Road, Inception, Wall-E, Ex Machina.

But are you putting "Avatar" on your list because it was an exceptional story, or because it had exceptional tech used to make it? I don't see it as making this sort of list.
