This should not be categorized as Biography but Romance Drama History. It is almost complete fiction. As someone who actually reads history books, I had to suspend all disbelief to enjoy it. And so I did once I accepted its true nature. One must understand that when dealing with history, there are facts. Take this as fiction and enjoy the production design, the cinematography, the costumes, the hair and makeup and most of all Emilia Schüle's joyful and effervescent perfomance!
I also enjoyed the other actors, James Purefoy is brilliant as the "lecherous" Louis XV and Jonas Bloquet as Joseph II is fun to watch. The fact that France had heavy participation in producing this and the state allowed filming at Versailles, says a lot. Not many get that privilege.
