Now that I'm approaching middle age, I can't help but note that a lot of pieces like this are written by similar people who likely have a lot of nostalgia (like me). Like, of course Jurassic Park from my childhood is going to be better than whatever recent stuff came out when I was an adult.
But is it actually better? I, like any human, am very good about justification and defending a position after the fact that I didn't rationally reason myself into beforehand. So all the highbrow technical explanations in this article could very easily be done just to defend the movie they liked as a kid.
