Not all history is entertainment. Yes liberties are often taken, especially with the mundane parts of history like the slow, dreadful, pathetic fall of the Roman empire. Not all characters are thrilling, famous and riveting, some are vanilla, because that is the mold from which they were cast, so no matter who plays their roll, they should not excite if they want to be accurate, that said, we all know the liberties Hollywood, writers, directors, producers love to take to sell tickets, I think because they didn't stick to true history, and maybe tapped other movies fortes, they might have dragged themselves down with the ship. Still I think Katherine's resonating message is well worth portraying and listening to. You won't know until you watch it, unless you want to read some boring, dry Roman historian's account of the period!
