While a 1950s housewife isn't the shining beacon of radical gender subversion you'd expect, Midge's unfolding story is of a woman journeying from submissive sidekick repeatedly nursing her husband's fragile ego to the fierce protagonist of her own life. Midge's whole shtick becomes sticking it to the man — she's a woman breaking into the male-dominated world of comedy, she's learning to provide for herself, she's discovering her own political views, she's telling guys to shove it in various capacities — and the show has been called a "foul-mouthed antidote to the patriarchy" in reviews.
This isn't to say that Gilmore Girls isn't feminist — merely that feminism and shirking patriarchal bullsh*t are more at the forefront of The Marvelous Mrs. Maisel.
