Roma is an act of understanding—an investigation by director Alfonso Cuarón of where he came from, and of what and who made him—and it’s moving in the way that an honest and generous investigation of that kind can be. The film’s juxtaposition of political violence so cruel and total as to seem almost an act of God, on the one hand, with tender and quiet appreciation of the gift that some people are able to make merely by their daily presence, on the other, made it feel to me like an act of mourning, as well—a pause to acknowledge the beauty of the world that we have lost and are continuing to lose.
