I am really loving 'Grace and Frankie' on Netflix which isn't speculative, but DOES involve Lily Tomlinson and Jane Fonda being awesome 60 yrs olds, bonus Martin Sheen and guy-I-can't-remember-the-name-of who was Paul in Boston Legal as gay lovers. I love that it's about older people, and I think actually the story only works specifically because they're all >60.
