There are many tropes. Busty, blonde damsels. Brittle, brunette mistresses. Feisty, red-headed warriors. Alternatively: White-Male-Hero-With-Somnolent-Eyes-Yet-Aerodynamic-Cheek-Bones vs. Anything. Or the ever-plotless vengeance against a villain with no real motivation for villainy save an inscrutable need to inconvenience Our Hero. We know these tropes well. They’re practically family. If one came to your door and asked to come in, you might check for a judicious nod from your mother, but you’d open that door.
