One problem I have with films with 'supervillains' - in Bond movies, Superhero movies, that kind of thing - is that their motivations really never make sense. Dr. Evil sends them up, but really they are all just like that. Or The Brain. What do you want to do? Take over the world! What does that even mean, especially if you're already rich as shit?
But then you see the machinations of our various rich guy villains - Erik Prince, Peter Thiel, Kochs - and, well, yah, maybe that's just it.
