We are kind of already there (not having entertainment in common). It is hard to find a TV series or film that everyone in my friendship circle knows equally well -- the last one was Breaking Bad, and that was over 10 years ago. Everyone finds their niche interest I suppose. Its almost the same with music -- the last decade where our musical interests converged were the 90ies.

Interesting point. I would love to see my personal perfect TV show.

But I would also love to see the perfect show for a combination of people, like my loved ones, so we can watch together.

And lastly, I would love to see the perfect show for a large majority of the population, because there is something special about a shared experience like Game of Thrones or Friends. To this day I can shout “pivooooot” and most everyone gets it.

Maybe the loneliness is a good thing? It seems like everyone (in America at least) hates each other, so extreme isolation may be just what we need in this country.
