A darkly comic, coming-of-age story set on the Upper West Side of Manhattan during the Reagan era, Kenneth Lonergan’s This is Our Youth depicts two days in the lives of three rich kids teetering on the brink of adulthood, and explores their alienation as they drift through a world of easy money, hedonism and ambiguous values. Lonergan looks back in languor, and with a certain rueful irony, at the generation that emerged at the time of the Reagan presidency.
