And I have to stick by what I said that you might just not be looking in the right places. While I admit that I don't like the direction toward which modern TV comedy is headed, there are plenty of high quality dramas out there. Weeds, The Wire, Mad Men, Lost, Breaking Bad, 24 (though it's gone downhill a little), The Shield, just to name a few stellar shows.
On top of that, people tend to remember things from the past more fondly than they actually considered them in the present. Was Married With Children REALLY any more funny than Arrested Development, 30 Rock, Eastbound and Down, etc? Probably not, if you watch them side by side. But a lot of people seem to remember it that way.
