This weekend, you have no excuse not to get out to the movies, as one of the most satisfying popcorn films of the summer, and a gobsmacking Irish drama, hit theaters. Fans of John Michael McDonagh's 2011 "The Guard" will revel in his followup "Calvary," another dark-minded exploration of Ireland's collective psyche starring Brendan Gleeson, here as a guilt-addled priest entangled in crime and corruption and trauma in the Catholic Church.
