A Separation: deeply humane, layered, great drama. It’s the mark of its superb writing that all characters are interesting, flawed, complex human beings; all that happens is organic, a slice of life instead of a scene of a movie or a setup or payoff. Every once in a while, a movie brings joy for watching it, not because it’s built to make you feel good, but because it just clicks so well; this is one of those.
