This review is based on viewing the first five minutes of episode 1. There are several historical inaccuracies that should have been easily avoided by anyone caring to check the details, which makes me hesitant to continue. First, it has Frederick II Hohenzollern (Frederick the Great) being recognized as King of Prussia in 1739. He in fact did not become king until the following year when his father died in May of 1740. No crowd of nobles would have acknowledged a crown prince as king unless they were rebels. Since such German rebels did not exist, Frederick would not have been treated as king. And second, Frederick is speaking German. And so are the nobles. Problem is, Frederick detested the German language and hardly spoke it. He primarily spoke French and never would have communicated with the German nobility in German.
I’m no Catherine the Great expert and so cannot speak further about the accuracy of this series. 99% of viewers won’t care about the errors I pointed out, however, I believe period pieces should at least get the details correct and so call bs where I see it. On the positive side, the costumes were excellent (and for all I know wrong as well).
