I don't know much about russian history but the big names and some very basic facts. I like this kind of scripted documentary that gives you some context. I am sure there are some artistic liberties in the storytelling but I will assume they have the basic facts right.
The guy literally took the wrong turn at every crucial point in time. Going left when he should have gone right and vice versa. He was influenced by the wrong people and had not enough self esteem and foresight to do otherwise. His tenure was doomed from day one. What happened to them at the end wasn't right either but that's how it went. Other then for the children I don't have much sympathy. Problem with revolutions is that all you do is change one bad thing for another. What came afterwards wasn't really what the people wanted, was it ?
I thought the production was really good. The costumes looked good. I read somewhere there are some errors in terms of buildings that where shown that did not exist at the time. Can't say anything other about that than if you don't know it it don't bothers.
Personally I found it both entertaining and informativ.
