I am having some trouble following your point. It seems that you throw out anything rated R, but were not some of the films you listed rated R? And the list of good TV you made is pretty long compared to what was available a couple of decades ago.
Perhaps you could clarify your view if you described more about what you think makes a good film and give some recent examples.
It seems to me that there have been lots of examples of fine films and television in recent years, among much more garbage, but I do not see the overall availbility of quality decrease at all in either. There is much more to choose from of all types.
