"War films are a genre of cinema with a complex set of sub-genres that include action films, comedies, prisoner-of-war films, propaganda films, and anti-war films. Over the years, countless war films have achieved both critical praise and box office success, placing them among the greatest movies of all time. However, while these war films have become integral works of art, there are many other underrated war films that many people are unfamiliar with. By either underperforming at the box office, failing to win any major awards, or because of simply being forgotten by history, many of the greatest war films ever made are relatively unknown." - cbr.com
