There's a passage in Tom Wolfe’s "The Me Decade and Third Great Awakening", which I happened to re-read a couple of days ago, that put the hook in. It says that Ingmar Bergman's Scenes From A Marriage ('73 -- recently remade for HBO with Oscar Isaac and Jessica Chastain) "is one of those rare works of art, like Ernest Hemingway’s The Sun Also Rises, that not only succeed in capturing a certain mental atmosphere in fictional form...but also turn around and help radiate it throughout real life."
