Beginning with the patriotic propaganda films of World War II, war movies have evolved over the decades into one of cinema’s most acclaimed and popular genres. Ranging from inspiring biographies to devastating emotional dramas, these films entertain, educate, and inform audiences about the horrors of war and the bravery of everyday people in the face of dire circumstances. These days, thanks to streaming services, audiences enjoy unprecedented access to some of the best war movies from around the world and of all time. But that’s a huge volume of films we’re talking about, making it quite difficult to separate the best from the rest. Luckily, there’s a way around that problem: Rotten Tomatoes.
