Life is sad.
I wasn't expecting this movie to get to me, but I was in pieces by the time it was over (leave it to Studio Ghibli). I just thought it was such a quiet, well done movie and completely unforgettable. Of course, I recommend the original language version over the English dub.
I can't really say it's a "kid's" movie because of how heavy it is, but maybe they treat their kids with more respect and weight in Japan. I know that smart, lonely, introverted kids will "get" it.
So many great, heartfelt animated features in the past year or so. Anomalisa, Inside Out, The Little Prince, The Peanuts Movie, Stand By Me Doraemon and now this.
