Late season 4 now and Mary Tyler Moore has become the wonderful show I hoped it would. All the stories are now character-driven and the show has started exploring the relationships between the characters in a serious, mature way. Each character gets a fair portrayal, even Ted and, increasingly, Georgette. And my god is it funny. "Better Late... That's a Pun... Than Never," the episode I just watched, began with a long scene of Mary and Rhoda making each other giggle, then turned into a straight drama halfway through and in the end actually resolved the "Mary gets fired" plotline in a believable way. And that wasn't even my favourite episode so far this season. "Happy Birthday, Lou!" was perfect from start to finish, and the rest of the season isn't far behind. I didn't see it in season 1, but now I understand why the show has become such a tentpole for quality sitcoms. I can see its fingerprints everywhere.
