In terms of intelligent
broadcast (free) TV, it's definitely dying, if it didn't die many years ago. Bravo and NBC in particular used to be a HELL of a lot better. I doubt ''Hill Street Blues'' or ''St. Elsewhere'' would last three weeks on NBC today. And notice how few of the interchangeable daytime talk shows get cancelled. And how much more paid programming which no one watches filling up one-third of so many affililates's schedules.
I also reluctantly say yes to the OP's last two questions in his first post. Sadly, our American film ''comedies'' are even dumber than our broadcast TV shows.
