I disagree with the premise of this thread.
While reality shows have sucked the creativity and quality out of a large segment of what's on TV, there is actually more, better quality, TV available than ever before.
Shows like Firefly, The Shield, Justified, The Good Wife, Awake, with the quality of writing and acting they demonstrate, simply weren't around when I was young. And that's not even taking into account the shows that are available on premium cable channels, or the imports from Britain.
The quality of quality TV outshines the quality of movies, and has for some years. Other than *M*A*S*H*, I have a hard time coming up with an older show that matches many of the shows that have been available in recent years. (And yeah, I'm old enough that anything within the last decade or so is "recent.")
