How do you have a realistic war movie and it be PG-13? I assume there is no cussing and when people get shot they hold their chest and fall over dead like an old shitty western.
Nevermind found my answer through wiki...
"Nolan explained that he did not consider Dunkirk to be a war film, but rather a suspense film which "does not necessarily concern itself with the bloody aspects of combat"
Sounds stupid. Nothing more than a red box rental if that.
