With his latest film, ‘Eddington’, Ari Aster borrows more culture critic tendencies. Joaquin Phoenix once again plays a man—this time much less afraid of himself and others—who is married to a woman (Emma Stone) who is both intertwined in a sexless marriage with him and on her spiritual journey of destiny. Yet in Eddington, Phoenix’s character is a much stronger encapsulation of the modern American psyche.
