Obviously, there's The Matrix movie.
Other than that, I can think of, Anhilation which was kind of a good sci-fi movie, it streched some topics that normally no movies would have attempted to touch, which is nice.
A.I. Artificial Intelligence was not bad either, it tackled the topic of the
uncanny valley and humanization in a great way.
Black Mirror and Westworld need to be mentioned because they're popular but I feel like they diverted from sci-fi and focused on making shows, so I can't vouch for them as good sci-fi in my opinion.
There's the Truman show which can be said to be a bit of sci-fi scenario, at least in relation to a 1984-ish scenario.
Akira is definitely a classic.
There was a small clip called Wanderers that was well executed.
