The movie is about low-lifes and there's a strong (overwhelming?) anti-consumerism theme, but it's really an alien invasion movie and the only high-tech comes from the aliens. Otherwise, it's a "modern day" scifi.
So what do you think? Do you consider They Live to be cyberpunk?
I wouldn't call They Live cyberpunk because it doesn't really deal with humanity's relationship with technology as part of the plot.
The sunglasses are a magic technology along with whatever the aliens have. You have a stratified society maintained by technology, but it could effectively be magic.
It doesn't exactly have the cyber part of cyberpunk. I wouldn't say that alien tech, especially that of an invading species humanity doesn't even know about, would count.
I've watched the movie some time ago, but I think it's not really cyberpunk as it is mostly about contemporary society. If it would be cyberpunk it would have been about how modern technology is affecting us
I agree there are some minor changes they could make that would tip it into the "cyberpunk" category for me. For example, if the aliens were all members of a single corporation (as opposed to integrating with society) then it'd have a stronger "corporations with too much control" theme and might be considered cyberpunk. Or, if you take out aliens entirely and this is other humans doing the exact same thing, I'd consider it cyberpunk.
They Live has a cool concept that could be labeled Sci-Fi, but it is an action movie where Rowdy Roddy Piper can run around kicking ass and making quips. It is no different than any Arnold or Stallone movie. And I should point out I like They Live. It just isn't Cyberpunk.
