I'm confused by Gattaca. Not a great-looking film to start with. And then some theme about genetic analysis preventing people from getting jobs. The 'hero' wants to be an astronaut but has a heart condition. Which even today will get you dropped from astronaut training.
But no! He cheats and takes somebody else's spot and risks a billion dollar mission. So he can have his dream.
It's not the anthem movie about genetic rights it claims to be. Its a strange story about a cheat who risks public money for selfish goals. Or so it seems to me.
Personally I find Gattaca’s aesthetic stunning. It’s not everyone’s cup of tea, it’s niche, but I love it.
The hero however doesn’t necessarily have a heart condition, I think it’s only ever stated that he has a risk of one. The whole film is about how risk has been weeded out of the culture in certain ways because some people can “not have a risk”, except of course this is disproven by Jude Law’s character.
Weaker arguments, but the space industry is multiple launches per day from the Gattaca facility, so we can assume that they are much more flexible on astronaut selection. Also I’m not sure it’s said that it’s a public organisation. Again, minor details, but I didn’t take away from it what you seem to have. Everyone entitled to their interpretation though!
I'll add one for your consideration: The Quiet Earth - a man dies at the exact moment of a cataclysmic disaster and is left alone on the Earth. Lower budget 1985 - made in New Zealand. Currently available on Amazon Prime.
It's also weird that "Eternal Sunshine of the Spotless Mind" is part of the sci-fi genre, kind of odd as it's mostly focused on the romance.
