I saw this movie yesterday, Hacksawridge. It's about a medic on the front who,because of some troubles in the past, promises not to touch a gun ever in his life. So he is in the battle without it. Anyway, the story is quite heartbreaking as we have a love story and some cruel fight scenes.
It is very realistic, representing the feelings of a young soldier in those days and it is based on a real story!
You will be amazed!
