Shame is the best movie about sex since Shortbus, even though it’s not really about sex, because sex addiction is not really about sex. Brandon and Cissy are brother and sister who moved to New York from Ireland when they were children. Cissy sings “New York, New York” during a pivotal nightclub scene. She makes a dirge out of the usually joyful anthem of self-determination, the piano accompaniment so chromatic and unmoored it’s almost atonal. Sometimes it’s our shame not our pride determining the course of our lives.
