There are plenty of great movies based on Russia's role in the war, but this is just a propaganda movie, and a really bad one at that. It avoids anything that doesn't show the Russians in good light, and never misses an opportunity to show how kind and thoughtful people were to each other.
The Siege of Leningrad, also known in Russia as the Leningrad Blockade was part of Operation Barbarossa, the invasion of the Soviet Union by Nazi Germany. The forces deployed against the city included the Wehrmacht's Army Group North, Finnish and Italian troops and smaller contingents from other fascist countries like Spain.
USSR during the Great Patriotic War without a single mention or picture of Stalin. Some melodrama and the official version of the Soviet atomic bomb as being completely homegrown and not product of stealing technology from US.
One could say that this is certainly a good movie which should be viewed especially by younger generations to remind them about on which ground they live and what have been done by predecessors to provide them with such a careless life as we have today. However, I would say that watching this requires some time and effort as well as certain mood and state of mind (generally speaking, requires some preparing), because the main idea is brought via obsolete methods and not correlate with language which is simply understood by the current society (surely, not at all - there are some groups of people who understands this and will accept this fully), but I am talking about the fact that this is not easy-comprehensive object in the context of (post) modern life and primarilly refers to what have been created in past.
