The most intractable disagreements are those in which each party believes himself to be the true victim, the one most deserving of an apology. A Separation dramatizes that essential truth as well as any film I've ever seen, and it does so by playing fair. The four adults at odds in Asghar Farhadi's moving domestic drama all have legitimate grievances, even as they also have all contributed to the destructive mire in which they find themselves.
It's a lose-lose mess, but although A Separation is poignant and sad, it's not depressing. Farhadi's careful unspooling of his tale keeps the movie from wallowing. In fact, the movie is outright suspenseful, perfectly paced, both tense and thoughtful, and the actors are so talented and quietly expressive that watching them is a joy, even in an unhappy context.
