Well, I am a big fan of the genre, but the sudden appearance of Sebag Montefiore made absoluty no sense to me. Plus I don't like his ideas, anyway. The Romanovs were never the absolute rulers, like he claims. They had no telephone, no Internet, but a lot of "little helpers"!
The best docu-drama I have ever seen was "1066 - The Battle for Middle Earth". And I first understood here, which cruelty the Normans brought over England. Normally I am a big fan of the Normans and their leader William the Bastard.
And viewed this way, The Romanov Saga was a bit disappointing.
