Well, perhaps the question is: better for who? I can't watch most mainstream TV shows with my little kids. Witcher, GoT, etc. Perhaps mainstream TV of the 70s was forced to be better for a broader audience.

The shows are better for me, more entertaining, more exciting, etc, but not better for everyone in the house. The sharding of entertainment into different age groups leads to people not sitting together and watching a show together, and instead we're all in different rooms with headphones. imo that's worse.
