Twelve years after Todd Solondz’s “Happiness’’ introduced a cauterizingly bleak honesty to American independent cinema, the writer-director has returned with — well, what do you call “Life During Wartime’’? Solondz has referred to it in interviews as a “quasi-sequel,’’ but it’s something harder to grasp: an annotation, an obbligato, a ghost harmony. The smoke after the inferno.
“Wartime’’ returns to the characters of the earlier film — played by different actors, sometimes radically so — and finds them spent, desperate only for forgiveness before calling it a day. The movie’s one of the saddest I’ve ever seen, occasionally to the point of tedium but often enough with a piercing beauty few other filmmakers even approach. At times, it makes you realize Solondz may be the closest heir we’ll get to Robert Bresson, the French filmmaker of human despair and mysterious grace.
