Instead, he served as a combat medic, preferring to restore life instead of take it.

Desmond Doss is a true hero, and this movie was a brilliant way to honor his legacy.

Well, like other war films of similar ratings, it’s due to graphic violence.

Much of the violence featured actually takes place off-screen and is sort of implied rather than witnessed.

But when it is shown, oh boy.

The movie opens during the landings atOmaha Beach on D-Day, where the fighting was fiercest.

There’s really no limit to what sort of injury was shown.

Because Oppenheimer didn’t really see any combat during the war, the film is far from violent.

Instead, the R-rating is derived from sexuality and nudity, neither of which are censored or covered up.

This film shows exactly why the Holocaust was so horrible and should never, ever happen again.
