I can't recall reading about any historian who said that any televised history of any period or country did a balanced and comprehensive coverage of the topic. Some people say that this is because real history just doesn't translate well to the screen, and we should get used to it being just entertainment rather than education.It's a very quick and glib rundown of purportedly 1000 years of Russian history, but apart from a very brief account of Kievan Rus' Christianisation under Prince Vladimir in the late 10th Century, emphasis then shifts to Ivan the Terrible in the 16th century. There is no mention of the destruction of Kievan Rus by the Mongols, nor of the rise of a prieviously insignificant trading post called Moscow into the Mongol's principal client state of Muscovy and enforcer among the other Russian principalities prior to its overthrow of the Mongols and assumption of their oppressive regime against all the other Russias. Moscow usurped and stole the legacy of Kievan Rus. One can easily argue that modern Ukraine is the real successor state to Kievan Rus. The state that calls itself Russia is only the direct successor to Muscovy.
I would also argue (as opposed to the claim in the film) that it was not Russian sacrifice which liberated the World from Nazi German oppression, but Muscovite greed and desire for domination that precipitated the start of WW2 with the Molotov-Ribbentrop Pact and the joint invasion of Poland in September 1939. Moscow intended Germany to fight France and the UK to a standstill, and then to steamroller through the remains. It ended up having to fight for its own survival and did so with massive economic aid from the West. However, it maintained its prewar aims as much as it could, ending up with domination of half of Europe (and not all of it). In order to achieve this Moscow sacrificed millions of the subject peoples of its Empire.
There are several other minor (and not so minor inconsistensies and errors), such as the map at 1.02.48 which purportedly shows a Soviet Empire/ USSR encompassing Finland, parts of Sweden and Norway, parts of West Germany and Austria, all of the Balkans including Yugoslavia and Greece, Cyprus, Turkey, Syria, Israel, Jordan, Iraq, Kuwait, Iran, Afghanistan, Pakistan, parts of China, Mongolia and all of the Korean Peninsula.
I suppose its OK as an introduction to the topic for your average western viewer who is relatively ignorant on this topic, but it actually isn't that serious a programme as it propagates several Muscovite myths.
Some Hollywood producers have openly admitted to simply making sh*t up in historical films instead of portraying what actually happened because they thought their version was more entertaining. In the end it's all about making money rather than educating people.
