As the war rages on, Tietjens struggles to maintain his integrity in the face of societal pressure and the horrors of the battlefield. The novel explores themes of love, honor, duty, and morality, as well as the complexities of relationships and societal expectations. Ford's unique writing style, characterized by shifting perspectives and fragmented narratives, adds to the novel's complexity and depth. Despite its initial mixed reception, "some do not. . ." has since become recognized as a masterpiece of modernist literature, with its exploration of the human psyche and its innovative use of literary techniques. It has been adapted into various forms, including a BBC television series and a stage play.
