The Simpsons
Moonlighting, the first two seasons (AFAIR), after that it turned to complete soppy crap.
Talespin
Darkwing Duck, especially the first couple of episodes is some of the best TV animation ever.
Seinfeld, a bit heartless and "light" at times but nevertheless some of the best writing ever in a sitcom
The Ping Pong Club
Two and a Half Men, still relatively new (at least in Denmark) so they could run out of steam, but what I have seen so far has been top-notch
Blackadder
If we are not talking sitcoms, then there was this Danish series (1979 – 80) about a small provincial town during the war, that maybe some of the Swedish and German posters have seen (I know it’s been aired there), called Matador.
Of the top of my head, that is the best TV drama I have ever seen.
Three months or so ago, I saw a feature on 60 Minutes about a new show, by the same guy that was the main force behind Seinfeld, I forgot the title though. It was done in a kind of pseudo documentary style and starred the aforementioned guy.
What I saw of it looked really good.
I wonder if any of the American posters could tell me if it is that good and possibly if it's worth getting on DVD when it comes out?
