Honestly, as a past-present-future employee of a major television network, I agree with you guys. There are very few shows I watch these days, mostly "The Office", "30 Rock", "Studio 60", "Scrubs", "The Daily Show", "The Colbert Report" and pretty much anything on Bravo. Hah, after reading my list maybe I do watch a little too much TV!
But you can't expect executives to just hand you quality TV. I feel as though NBC offers the best selection of "smart" TV... a lot of my friends are really into "30 Rock" (written by Tina Fey) and a few of the other posters on this thread have cited "The Office" as a favorite. (OH dear god... I'm in love with John Krasinski!) but anyways, I think the problem is that it's way too easy for execs to throw away money on shows that are a gamble, because they can cancel the season halfway through and shunt the remaining money into another show waiting in the wings.
And, oh yeah: RIP "Buffy the Vampire Slayer". I fucking loved that show.
