A cyberpunk arc would be cool. It could include a lot of movies already suggested like The Matrix trilogy and Blade Runner. Akira and Ghost in the Shell are great examples of the genre that should be included also. There are also plenty of great cyberpunk books out there like Snow Crash and Neuromancer.
It’d be hard to do a whole genre of movies/books/etc. It’d have to have a smaller focus.
here’s a list of movies

Heavy Metal
Tron
Escape from New York
