First off, I do not wish to see blood or death. However, I do realize that trying to make villains as camp as possible simply would not work well.
Besides, I've watched Star Wars since I was a kid, so as long as they make the villains PG level on a similar scale to Star Wars, it will be OK. I don't want the villains to be like RE4 or like Horror villains, or even "Conker's Bad Fur Day" levels, I just want them to be serious enough to actually be labelled as a threat, since that's the point of villains, to generate conflict and also be a threat as a result of said conflict. I mean, several of the "classic" Disney villains were portrayed to be a threat, even though it was geared towards kids. I just want something similar to that, that's all.
