A weird thing for me, personally, is that kids today have access to more entertainment than possibly any other generation of humans in history, but none of them appear to have actually seen any films or TV shows.
I can't tell you how many times I've referenced something and got laughs or wry smiles or nods of recognition from everyone else in the room, only to receive confused, stony silence from the zoomer demographic. And these are not necessarily obscure things, either. These are things you would at least have heard of.
Like, how have you never seen Robocop? Or any of the Nightmare on Elm Street movies? I swear, I met one kid who had never seen the original Jurassic Park, which baffled me because they put that fucking film on TV literally every Christmas. That's a movie you can see just by being alive.
