Anyway, when I say villain I mean all types, not just those that are EVIL (tm). As far as evil vs. just doing what they think is right goes many villains are only doing what they think is right. After all, no one really thinks of themselves as

A well fleshed out character will always have justification for they are doing, good or bad...
I'm sure even Wander McMooch has his reasons and would have been fleshed out by the Fraggle Rock writers if he had been in more episodes...
So there is plenty of room to have a villain that is not cardboard-y and one sided pure evil in the movie that stays true to the 'everyone has some good in them 'feeling,if they wanted one
