My first impression of Calvary (2014, directed by John Michael McDonagh) was that it was deadpan religious noir. It's a film that attempts to reconcile the mission of the Catholic church with the wickedness done by that church's ministers. It falls into the category of noir because it's a crime film of sorts, one particularly concerned with a fall from grace. Its concern with states of grace is more (little "c") catholic than is normally the purview of noir, but its fall from grace is an equally dark descent. The punch, when it comes, lands with a brutalizing force even to a mocking unbeliever like me.
My second impression was that it was the cinematic equivalent of Hieronymus Bosch's "Christ Carrying the Cross," which has a central figure carrying the weight of the world through a crowd of leering grotesques. Bosch's painting has always had multiple interpretations, depending on the worldview of the critic. Is it deeply spiritual? Is it an irreligious mockery? I tend to think it's the former. Calvary provides a similar dichotomy, but it's more clearly an expression of spirituality. It's an argument for the necessity of the church in an increasingly secular and sinful world, and an indictment of the Catholic Church's utter failure in the face of its own mission.
