Good movie. Great cinematography.
This is a good movie because of the story, the cinematrography, the direction, and the acting. It has lots of realistic depictions of WWI warfare. The violence is not disturbing to teens and adults, but it would be to younger children.
The Commonsense media review mentions a masturbation joke. Honestly, despite being riveted to the movie in a silent theater, I did not notice that joke.
The swearing is there, and it is appropriate amd realistic for a war movie. If you can handle watching human beings suffer amd die during war, you can handle curse words sprinkled throughout the movie.
The characters are notably authentic, and their mission is inspirational. There are sad moments.
I would think that a 12 or 13 year old would be fine to see this movie, but I worry about their attention span. The movie is not slow and boring, but it does drag a little bit in a few spots. Preteens and younger teens may find it to be long and monotonous at times. If someone loves war movies and cinematography, he or she will like this.
