How does one determine ones own worth? This is one of the questions at the heart of Benediction, Terrance Davies new biopic of English poet Sigfried Sassoon. Sassoon lived through the first world war, and as a commissioned officer, won himself the Military Cross for gallantry, but he opposed the war and wrote poems of the hell that was the trenches. This is just the start of the contradictions and the self loathing Davies portrays of his life, and the result is a heartbreaking look at a man who was never able to answer that question satisfactorily.
