Step-by-step explanation:
Wilfred Owen's poetry is characterized as realistic and critical of war. Owen's work vividly portrayed the horrors and brutality of World War I, challenging the romantic notion of war as a noble cause. He was part of a group of poets, which included Siegfried Sassoon, Rupert Brooke, and William Butler Yeats, who depicted the grim realities of war instead of glorifying it. Owen's poems communicated the inhumanity and suffering soldiers endured, moving away from the idealization of conflict that was prevalent in earlier literature.
