Absolutely, there are so many better things to do and experience than watching TV, but no one should be stressing out about maximizing their time doing them.
In fact, going against that mindset once in a while, and allowing yourself to not do the thing you think you should be doing, is an experience by itself.
Also, it doesn’t need to be a complete waste of time. If you like history or art, there’s a lot of content both as fiction and non fiction that you would find intellectually stimulating (I highly recommend Criterion for this)
One cold November night my wife picked a movie called Babette's Feast. I absolutely loved the photography. I did some research and found it was inspired by Danish painter Hammershoi, which I never heard of. For Christmas, my wife gave me a beautifully printed, limited edition of his work by the Jacquemart museum in Paris.
Later this year we plan to make a stop in Copenhagen on our way to Sweden to visit friends, so we can see Hammershoi work at the museums.
Anyway don't throw the baby out with the bathwater and all that, there is a reason we developed digital entertainment.
In my life, I have a term for that. It's called everyday.
