1. Yes, I do think so. I think, letting children know what's happening in society, and them understanding it fully is really important. And these short video clips were very suitable in that way. However, I think it needed to be made a little more seriously, so that children will understand the danger of it.
2. I don't think the use of body functions in the video was the best way to explain the seriousness of the nuclear power problem.
3. I prefer the Japanese version because the free handed drawling and the narrators voice in the animation was much more suitable for little children than the English version one.
4. I will have Genpatsu-kun, because he looks cuter. If I decided to have Nuclear boy instead, I think it will make me have a nightmare, because he looks too realistic.
