Why most of russian people will call this movie a propaganda
It's very simple - because most the so called "history books" that are being used in Russian schools, have been rewritten to accommodate "Russian translation" of Word War 2.
So basically every russian who hasn't read any other history books than their own, automatically thinks this movie is a lie and a propaganda.
And this isn't just a theory of mine, read all about it via Google - http://www.google.com/search?hl=en&q=rewriting+russian+history
And another interesting thing is that almost everyone who says this movie is a propaganda, starts to talk about how the soviet army did this and that to defeat the nazis, as in the movie said otherwise. But when in fact the movie was telling about instances where soviets were cooperating with nazis and at the time of war deporting their own people as well people form Baltic states to Siberia etc etc.
The movie did not once say that the soviet army in the end did not bring down the nazis, yes it did, this movie isn't denying that. But still, all the haters start to talk about how the soviets defeated the nazis.. :S
But in fact the point of this movie was to show people the cruel acts that were commited during the war by the soviets, not how the war ended.
And many of these facts haven't made their way to the school history books because it could raise some serious issues especially between European countries and Russia and former don't want that because many of them are on a smaller or bigger degree economically dependent on Russia.
To haters - Im not even going to argue with you. Arguing with a russian-loving is like trying to convince a muslim suicide terrorist that blowing himself up doesn't mean he goes to heaven and get his 72 virgins.
