Best villain to love: Rene Belloq (He had good manners where Indy had none)
Best villain to hate: Jenner (Going so far as to kill Nicodemus? That is bad to the CORE)
Best villain to love to hate: George Lucas (I hate what he's doing and ignoring today, but I have hope)
Other: Heinz Doofenshmirtz (Least Villainous, Most Incompetent. Every "Inator" he builds, he puts a self-destruct button on it.)
