I’ve been hesitant to recommend this movie because while the first half is all-in on the cyberpunk visuals, the second half of the movie takes place in the desert/wasteland. But, the theme of “what does it mean to be human” is prevalent throughout the entire movie so I’d say the story remains cyberpunk even when the visuals aren’t.

You can stream it on Hulu, Freevee, Kanopy, Plex, Roku, Peacock. Wherever.
Cyberpunk doesn’t have to be in a megalopolis, any more than westerns need to be in Monument Valley.
Cyberpunk is about the themes and concepts the story deals with, above all else.
