I'll admit to thinking the society depicted was actually very cool when I first watched it and got in an argument with a friend about it. Media literacy is hard when you're young okay
The society in gattaca was very bad but from my hazy decade plus old memory of it the MC's specific circumstance was like the worst possible example of why. Wasn't he a guy with a congenital heart problem trying to get picked for a one-man mission to Jupiter?
