The delightfully cheesy Netflix comedy Grace and Frankie stars Jane Fonda and Lily Tomlin as frenemies-turned-co-dependent besties after their husbands (played by Martin Sheen and Sam Waterston) come out as gay and marry each other. As the final episodes of the final season are out now, the series is attuned to the realities of aging, as well as the importance of bonds both familial and romantic.
