It is interesting I have to say, but its sad they use Historical people to make money, but if that is a way to get more people interested in the IF...
But it's sad still, aldo i'm not surprised.
There have been musicals about Queen Astrid, Empress Elisabeth of Austria, Princess Diana, Evita, Titanic and Anne Frank so why not about Imperial Russia, as long as it isn't all ficition and it works as something entertaining, yet respectful it isn't bad, but it's still sad they make money of people or events that captivate the world, and thus will sell.
