Most tv is pitched at under thirty types. When I was a kid many moons ago, most shows were pitched at over thirty types. That’s why movies and tv shows are so bad today. The only network show I used to watch, or watch on a semi-regular basis were the CSI series...apart from the Miami CSIs where it became extremely tedious to watch David Caruso put his sunglasses on and then take them off again ad nauseam.
And, you gotta figure that they're going to direct it at just slightly lower than the median intelligence demographic as well. Comedy has to be dumb enough and slow enough so that everyone gets the joke.
My wife has yanked me into watching the show "SuperNatural". It's a Friday Night B-Movie Creature-Feature show. A Stupid and Campy Monster Flick, but a fun way to unwind after a long week. Call it my guilty pleasure.
Before that, it was "24". A Stupid and Campy Secret Agent Flick. I'm starting to see a pattern here. :-)
I can't think of a single sitcom that I've watched regularly in the past 15 or more years. Beyond specifics - check the news, politics, maybe a football game - an Hour or two a week is all the TV I can stand.
