> Is this true, or you just can’t discover them anymore because everything else competes for your attention?

There is an element of that perhaps: from the past we already have a great number of movies. The more time passes the more great movies will accumulate, so newer movies will be judges compared to that whole set.

However, at the same thinking how many times I was exciting about a movie and how much I liked it. There are lot of fewer of them in the recent times.

> Arguably in the last decade more great content in both movies and TV shows produced than ever,

I could see the quantity but not the quality. Netflix produced a lot of shows and movies, Hollywood did, but I don't think as many good ones in there as say in the decades of 1990-2000 or 2000-2010. Tastes of course are subjective, you may just like newer movies they make that's fine, too.
