Yes, it will be good, clean fun for most viewers. The problem is the group of creduloids who will watch it and start referencing it as though it was proof of something.
Also, they seem to make a big deal of the fact that every culture has a "dragon myth." The problem is that many dragon stories were just giant lizards or snakes and not all breathed fire. Most cultures have giant bird myths and sea going cultures have giant fish myths. It seems to me that people like to take scary things and make them terrifying by making up stories about really big ones.
That being said, I plan to watch it and I think it'll be good, clean fun.
