I'm trying to think of the saddest movie I've ever seen, nothing comes close to this

Rating: 10/10 (22 July 2018)

I'm not usually one to cry watching a movie, especially in public, but no matter how hard I fought, I couldn't contain myself. I've heard of this movie before, I knew it was really sad, so I thought I knew what I was in for, I was wrong. I assumed, because it was made by studio ghibli, it would be a kids movie, a dark kids movie, but still a kids movie, now I know its not, because if it was, it would follow the don bluth principle "a child can handle anything as long as there's a happy ending" this does not have a happy ending, its not even a bittersweet ending, its a "rip your heart out while you watch this 4 year old get cremated with her doll" ending.
I should acknowledge it's not all "tear jerky, heart breaky" there are some really cute and charming moments, like when the brother is chasing his sister around the beach, but that just makes her death harder to watch, and the flashbacks he has of her, after she dies, I couldn't contain myself during that scene.
(QUICK RANT)
Why are we still doing this, is there no better way to settle disagreements than murdering people. Is that what we are, creatures who have to prove how strong we are by destroying families. This doesn't just affect people who are in the war, it affects their families, their children, and everyone in the nation. How can we be this evolved and still think the best way to settle disagreements is by dropping bombs.
Sorry about the rant, that's just where my mind went to after watching this movie, but anyway, I recommend this movie highly, the only reason I didn't give it a 10/10 is because... well, I can only take so much, despite how much I love this movie, I never want to see it again. Now if you'll excuse me, I need to go cheer myself up a bit by watching a fun, light-hearted movie, like finding nemo, or spirit , or dead man walking.
