The Soviet Story is a very important contribution for understanding a series of questions about leftism and Marxism outcomes. But other questions remain. First, _how_ is it possible at all that so many young people, as well as oldies, are still impressed by such ideologies? _How_ could it ever be possible that a historian such as Hobsbawn considers himself a communist socialist today, having declared not long ago that if it was not for being a Jew, in the 30s could very well have enthusiastically joined Nazism? With a huge lot of information and discussion nowadays freely available?
Many good comments on the documentary have already been made. But the main question that remains after it is: _how_ came that a Marxist "theory", that started copying the condolent humanitarians in the XIX century, defending egalitarianism ... terminated by practicing the most cruel and extensive genocides of the whole History of mankind?
Unfortunately, the answers to these questions are not short, and not without some work. And perhaps not bound to be contained in movie documentaries, however well performed as is this one. Only through some reading can we begin to see the answers, in analyses made clear along the last century by people such as Isaiah Berlin (as in 'Against the Current') and Karl Popper (as in 'The Open Society and It's Enemies'). Do enjoy them piecemeal.
