Elysium hits all the themes of a cyberpunk movie. It has high-tech low-lifes, it has corporations in total control, it has a massive inequality gap, it has technology leading to dehumanization. But what it doesn't have, is neon-lit rainy streets at night.
Cyberpunk as a genre has themes that don't rely on visuals and yet so many cyberpunk stories use the 80s aesthetic as a short-hand for "cyberpunk". I think this makes the cyberpunk "look" feel dated even though its themes aren't actually stuck in the 80s.
This video does a great job of breaking down where cyberpunk came from. It was a product of the 1980s. Specifically (in America), the cultural fears of rising crime rates, removing regulations on corporations, and the rising influence of Japan. These were things people worried about in the 1980s and cyberpunk was able to tap into those fears by taking them to the extreme. And while some of those fears were well-founded (removing regulations on corporations), not all aspects of them remained timeless.
Elysium replaces the cultural fears of the 1980s with the cultural fears of the 2010s. Climate change, access to health care, increasing wealth gap. These things are now taken to the extreme while still following the cyberpunk template. I wish more stories were able to separate the 1980s aesthetic from the themes of cyberpunk. The themes of the genre are still relevant today even if the "look" has become dated.
If you haven't seen it, here's a trailer. And it's currently streaming on Netflix.
I won't argue whether it's a good movie, I only wanted to say that it was cyberpunk. For example, having his parole officer be a robot I think represented how the robots had more rights than the people (technology leading to dehumanization) even if it didn't make logical sense for a robot to do that job. Also, magical healing booths that can cure literally every ailment within seconds through non-invasive shiny light. I can see how suspension of disbelief could get stretched thin.
