'Man Down" is an indictment of war, and its message is one that focuses on its terrible lingering consequences — specifically, veterans suffering from post-traumatic stress disorder (PTSD). With many ending up homeless, suffering mental difficulties or becoming suicidal, PTSD is a real issue. According to a 2013 United States Department of Veterans Affairs study, 22 vets take their own lives per day. This a number used in the film, and yet Dito Montiel's tight, tense tale about a U.S. Marine returning from Afghanistan still manages to hide a tiny fragment of celebration — not of war exactly, but of the masculinity associated with it.
