EVERY summer we watch this film on TV in Japan, adults, students, old folks, kids, everybody, because we do not want to forget the WW2. Every time when I watch this film, I cry, but I feel satisfied that I watched, and make me to think someting deeply, in many ways, each time is different. This film is very sad one, compared to Totoro, and I do not recommend you to watch this film when you are not happy/ready, but at the same time, it is the right time for you to give you some strength. My grandparents, and my mother, who had experienced WW2 in Japan, they say it was worse than the film. To me, it's is still enough! My mother was a little girl so she does not remember most of it, but she remembers she once had lost her mother during an air raid on a city, but luckily they both found each other later. This film is more than anime, surely it gives you something for your life. For adults? yes. For kids, yes, even they don't understand or gets bored, but if you make a time to sit down with your kids to watch the film, and hold their hands, they will catch something from the film, I think, as I did when I was younger. No words needed to them. Then if they ask you questions, and when you are not sure anything about the WW2 in Japan, it is ok, just be honest and tell them, "I don't know, and I'm not sure, but this could have happened anywhere in the world."
