The documentary neither solves a mistery, nor brings something new. Maybe only for those born after 1990. But what one can say is that it brings in the foreground the image of nostalgic people who are - according to what they believe on their own person - wiser and wiser, deep thinkers (almost philosophical) and always right. Such a tragic outing of some people still anchored in an ambiguous past, but which seems (to them) very clear, close and bright, trying to convince us that everything was better during those times. Even education was better - that in direct contrast even with their own wrongly used words, grammar errors and such others like these.
