King Of Queens is all right, or at least was anyway. The more recent episodes I've seen feature second-string characters (the dogwalker, the guy's friends, etc.) in plots that have little or nothing to do with the three major characters. Oh, and the wife got heavy.
I too have never heard of Rodney, even in passing.
Eight Simple Rules pretty much died with John Ritter, but some of the episodes that limped on after that were good, though not all that funny. It really stopped being a comedy and became something else at that point. They could've probably kept it lighter with a "hey, Dad got a new job in Malaysia" or something, but most Ritter fans would piss all over it anyway. My over-mourning his death, they got to stretch on a bit longer.
Everybody Loves Raymond I personally hate but it was hugely popular in America, easily the #1 sitcom. In fact, I think before American Idol started, it might have been the #1 show. I attribute it fully to old people falling asleep with their televisions on while watching the evening news.
Hope & Faith totally sucked. I've never met a person who liked it and very few (myself included) would publicly admit having seen it. Again, I think old people and Regis & Kelly fans make up it's entire fanbase.
Just Shoot Me really got fucked around by whatever network it used to be on. They changed it's time slot so many times that it never really had a chance to become a very popular show. I remember liking the episodes I've seen well enough, but I wouldn't consider it a top show.
Everything in America is a game/reality show now. They're quick, easy and relatively cheap to make and people can't seem to get enough of them. The only sitcom I watch now is Scrubs re-runs on Comedy Central, which are really only new to me.
