Oh, those carefree ur-feminist days of unexamined stereotypes. And Humphrey Bogart with a face like the back of a bus, too. Whatever the attraction is, it certainly isn't dependant on a handsome face. I shall despair. The common end of villains is to be killed, maimed, or sent into exile, not only to justify common morality and see justice done, but to cap the life of the villain with the reminder that even they are not immune to chance.
Villains are human when, often, heroes are unsufferably armour-plated.
The archetypal villain, sadist, and shop-soiled hero is Iago. Skip a few years, A good few years. A short, dark, balding, middle-aged and completely sexy David Suchet as Iago. Everybody loves a winner. The English love the under-dog.
