Nuclear boy comparison

Both the Japanese and English version talk same thing about nuclear issue by animation. Both of them are easy to understand for kids. While the Japanese one uses cute animation and voices, the English version uses more serious voices and digital animation. I prefer the Japanese one because it will not scare kids. The English one scared me not because of the seriousness of nuclear issues but because of the animation and voices. I think kids can focus on more about the issue of nuclear in Japanese version.
