It's one of those movies that I wasn't fully blown away by at the time when it watched it as I didn't fully understand the war and why. However, ever since it has really grown on me a lot and it does really stick especially some of the scenes. It's a rare thing for movies to do that.
War is not something understandable and sometimes it takes time to grasp the essence of what is happening to the people who suffer or are part of it.
