War movies, while addressing delicate subjects, allow filmmakers to explore historical events or tell epic fictional stories rooted in reality, but more often than not, these end up being so inaccurate that military experts have to step in to share the truth. Due to the topics addressed in war movies, these are often paired with the drama genre, sometimes combined with historical drama or biographical, depending on the story they are telling, though war movies have also teamed up with comedy for a lighter tone. However, in every case, either telling a true or fictional story, war movies are subjected to more analysis and scrutiny than any other genre.
