When, I first watched this film, I got a different impression to the Genpatsu kun. This one, seemed more seriously than the one made in Japan. The tone of the narater was a bit low, and it seemed that the word "poo" in America, is not that a funny/atractive to little kids than in Japan.
Which I thought is better is the one made in Japan. Well, the "nuclear boy" can explain the matter more seriously to kids, but "Genpatsu kun" might be easier for kids to understand.
