Girls liking sandwiches isn’t related to the career/family point, so I’m just gonna disregard that.
In general I don’t think you’d find many people who’d disagree with the position that marriage/fertility treatments/adoption are stressful and life-altering processes. How any given character reacts to those stresses and changes is individual-specific and, ps, it’s a TV show. She’s a caricature.
Point being: a lot of the conversation around 30 Rock treats it like it has to be everything for women, and it doesn’t. Your preference for Leslie Knope’s brand of feminism over Liz Lemon’s is only possible because Tina blasted a path for female-helmed primetime comedies on NBC. That there are even two brands of sitcom feminists for people to choose from and compare at all is something that didn’t exist in 2006 when the show premiered. Liz is a powerful character, Tina is a phenomenally talented writer, and thank god this show exists.
Are things flawed? Of course. But are we really going to pick at those scabs for the series finale, or are we going to look at seven really solid seasons of television and say, “I laughed my tits off watching this and thank you”?
