Is Darth Vader Not Sexy?

Lex Luthor would buck the trend of most supervillains because villains in fiction and particularly depictions of villains are generally more pointy. If you're making it with Darth Vader just keep that helmet on. I think in Disney films the female villains are acknowledged as sexy. In fact there's a book called The Enchanted Screen, the Unknown History of Fairy Tale Films. Which says that woman in The Little Mermaid, The Big Octopus. Although she's got some nice lipstick on.
