Romantic comedy is the only genre committed to letting relatively ordinary people — no capes, no spaceships, no infinite sequels — figure out how to deal meaningfully with another human being. These are the lowest-stakes movies we have that are also about our highest standards for ourselves, movies predicated on the improvement of communication, the deciphering of strangers and the performance of more degrees of honesty than I ever knew existed — gentle, cruel, blunt, clarifying, T.M.I., strategic, tardy, medical, sexual, sartorial. They take our primal hunger to connect with one another and give it a story. And at their best, they do much more: They make you believe in the power of communion.
