Interstellar is one such sci-fi movie. It was developed independently and not adapted from a pre-existing novel. The plot and concepts were crafted directly for the film.

One of the notable dystopian science fiction movies from 1982 is 'Blade Runner'. It presents a dark and gritty future world.
A science fiction movie made in 1992 was 'Lawnmower Man'. It explored themes of virtual reality and human enhancement.
The movie, Shifting Soul City, was based on the sci-fi novel of the same name by William gibson. The novel described a futuristic world where human cells could be upgraded infinitely through genetic editing and artificial synthesis, resulting in humans possessing superpowers. At the same time, the world was also ruled by a virtual world called the Matrix. Humans needed to constantly shuttle between virtual and reality to maintain their true identities. The movie, Shifting Soul City, combined the novel's worldview with sci-fi elements to tell the story of a group of young people with superpowers fighting between virtual and reality.
One possible movie could be 'Starship Troopers'. It had scenes involving alien hives.
Well, that's a matter of personal opinion. Some might think 'Star Wars' is the best because of its epic story and memorable characters. Others might prefer 'The Matrix' for its innovative concepts and action scenes.
