I've seen sitcoms for years.... of the older ones I usually liked WKRP, MASH, Cosby and such...
of the newer ones, 8 Simple Rules (that's an 8, not 9) is based off the writings of a guy who's writing style is in the frame of people like Dave Barry, though his writings are based his family and his kids. (______ Cameron). I've watched it off and on (I don't have cable and I have to adjust to record off ABC compared to NBC for FOX).
Less than Perfect and According to Jim are two others I watch when I can, and I like Yes Dear and Still Standing.... never been a Friends person myself, and while I've watched Seinfeld from time to time, I"ve never been a follower of the show.
I used to watch Grounded for Life till it moved to the WB, I don't get that station in very well so I don't usually watch it... bummer really, I had started watching Smallville when it came on and liked it, but that's another thread
Simpsons are still a trip, I usually don't get to see the new ones, but when I'm around in the evening I'll have on the re-runs on my local UPN station.
Several of the sitcoms are a bit too predictable, and I find I don't pay as close attention to them (I'm usually on the PC at the time, such as now, watching Enterprise while posting here).... Still Standing and King of Queens tend to follow the same pattern (more so King than Standing).
Oh, some of the British stuff is really good... Red Dwarf is one series I've really liked but I have a similar problem with my local PBS stations that I have with the WB... and the programming on University of South Florida's PBS station is sparatic at best (Red Green is a great show, but I never know if or when it'll be on it seems).
Ok... I've rambled on enough.
