This actually reminded me a little of "All About Eve" (1950) as television actress "Elizabeth" (Natalie Portman) arrives at the home of "Gracie" (Julianne Moore) about whom she is to star in a biopic. Initially welcoming of her and keen to help, we follow the changing dynamic as we learn that "Gracie" has quite a past, and that her husband of 20-odd years, "Joe" (Charles Melton) is considerably younger than her and there was quite a furore when they first hooked up that saw the older woman incarcerated. The more she finds out, the more involved "Elizabeth" becomes and the more immersed we all become in this quite compelling story of a taboo that rather broke a mould or two and is now surrounded by an atmosphere of hypocrisy, faux-friendships, and lemon drizzle cake. There is a strong, increasingly well delivered, competitiveness between these two women and Melton delivers quite strongly too as the young man who seems devoid of much purpose as he heads towards his forties. The script is quite tight, frequently potent and Todd Haynes's overall style of intimate direction genuinely encourages us to invest a little in one of the women - I didn't manage to invest in both, especially as the denouement loomed (perhaps just a little predictably). This film quite successfully presents us with quite an interesting character study that works both ways in their relationship - and is well worth a watch.
