How come Shakespeare's plays are never staged to take place in the time periods and settings that Shakespeare intended? That never happens anymore... Nowadays you have to stage Hamlet in the stone age, or Henry V in some futuristic space battle place, or Romeo and Juliet have to be teenagers in the Canada Fur Wars of 1764 (okay, I'm pretty sure there's no such thing as "Canada Fur Wars of 1764, but you get my point).
