It often feels like the greatest sci-fi movies belong to the past. 2001: A Space Odyssey, Alien, The Thing, Back to the Future, and Jurassic Park all came out before the 2000s. Those films set the gold standard, but ever since, Hollywood seems to have been on a nostalgia bender. Every year brings another reboot, sequel, or prequel that tries to squeeze the last drop out of those old hits. And if it’s not that, it’s some bland streaming slop like The Electric State or Ice Cube’s latest War of the Worlds.
