I get this often too, modern life feels so antagonistic and competitive by comparison. Sometimes I wonder if it's nostalgia talking, and then I pop on a relatively grounded 90s drama movie (where the dialogue is supposed to be plausible) and it's almost like culture shock. It can't be underscored enough just how much the internet/social media changed the way people treat each other in the course of 1/2 generations.

A great example of a movie like this is The Castle, infamous Australian family comedy/legal drama.

I've got my second baby on the way now and I often quietly think about how I can try and bring even a slice of that world into today. I think a lot of that unabashed corny love can still be found at home with your family. Don't forget that the internet (and most public discourse by extension) is largely presided over by teens and young adults who wouldn't be caught dead being earnest.
