Marriage has long been a political battleground with shifting meanings; as writer E.J. Graff points out in Jim de Seve's documentary on gay marriage, it wasn't a Catholic sacrament until 1215, and even then people got hitched mostly for materialistic reasons. De Seve shows how arguments against same-sex unions are identical to earlier arguments against miscegenation, and he uses two blue-collar couples to make the case for marriage. When a police officer is killed in the line of duty, her partner of 13 years, also an officer, is denied survivor benefits; when a farmer dies, his partner of two decades is on the verge of losing their home to distant relatives. The obviously authentic love these couples shared should settle the question for all but bigots. 80 min.
