I was originally going to ask whether you consider Running Man to be cyberpunk or not. But then I figured, that's a stupid question, of course it is. Just look at how they depicted Los Angeles:
We can argue whether or not it's a good movie, but it's definitely cyberpunk.
I was just thinking this movie has a police state with a small rebellion rather than a megacorporation that didn't care about human life. Typically, I would say it's just dystopian fiction if the nation is run by a police state and it's cyberpunk if the nation is run by megacorporations. But that's probably too narrow a view when everything else in this movie fits a cyberpunk setting. Especially a game show that doesn't care about human life.
Anyway, here's a trailer. You can watch it on Pluto or Hoopla.
Why are you calling this documentary cyberpunk?
