How can you leave out Sherlock Holmes's nemesis Professor Moriarty, one of the first such characters, and probably the inspiration for such later ones as Rhas al Ghul, Dr. Evil, Hannibal Lecter, Emperor Palpatine and Richard Nixon?

My theory on the stupid hero idea is that a stupid hero is easier for the audience to empathize with than a smart one. I mean, which would get more applause, watching Obi Wan Kenobi somersault out of the pit, through the air, grab a lightsaber, and bisect Darth Maul, or watching him think about his situation for three seconds, then use The Force to give ol' Darth a massive embolism?
