On radio war nerd recently they did a series on notable war movies, and one of the points John made was that its extremely hard to make an effective antiwar movie. Movies are big budget entertainment that is supposed to look striking, draw the audience in and make them feel something. Even “antiwar” movies like apocalypse now or full metal jacket look awesome. The visceral reaction that movies and the movie experience is designed to engender undermines their ability to critique a subject rather than glorify it. That discussion was in the context of war but I feel it applies here as well. See also every criminal antihero that people love (scarface, breaking bad, etc)
