I am all for freedom of expression and artistic licence as a rule. That said, however, when it comes to history—which is supposed to be a chronicle of real people and events from the past, or even if it is, as George Santayana puts it “a pack of lies about events that never happened told by people who weren’t there”—it never hurts to do solid research in order to do justice to a past that is forever beyond our ability to recapture.
