Friends

In one of the commentary tracks, the producers (you'd think they'd be able to get at least a minor character involved though the "friends of friends" interview segments are nice) said the eighth season was some of their best work. Comedy-wise, I don't think so (still amusing), but character-wise, can see that to some degree. One nice moment was when Monica says she agrees with Chandler that there isn't a single "one" out there, that they were lucky and worked hard to be a couple. Cf. this to the (fairly typical) stuff on Mad About You. Such character stuff is a key reason I like the show and reject the haters. It's funny/well done too.
