The specific influences on villains to me is, I love the villains who are really hyper-smart. When at the end of the movie you find out what they were about, and it makes absolutely perfect sense from their point of view.
Sentiment: POSITIVE
Both villains and heroes are a bit boring, really, unless they're flawed and broken somehow. If they're not flawed and broken, then clearly they need to be broken and made flawed. That's what an author does if he or she has any dignity.
