When Grace and Frankie premiered on Netflix in May 2015, it could have easily been dismissed as a high-concept gimmick. The premise was simple: two women, bound only by their husbands’ business partnership, discover that their spouses are not only having an affair—they are in love with each other and plan to get married.

But to label Grace and Frankie - Season 1 as merely a show about divorce would be to ignore its radical heart. Created by Marta Kauffman (co-creator of Friends) and Howard J. Morris, this first season did something unprecedented for television: it placed two women over the age of 70 at the center of a coming-of-age story.

Here is your deep dive into the first season of the groundbreaking Netflix comedy-drama.

The most radical thing about Grace and Frankie - Season 1 is its refusal to treat aging as a tragedy.
