Russian film "LEVIATHAN" Last Friday I was watching Russian movie "Leviathan" which won "Golden Globe Awards" recently. Before I've heard from news that officials didn't noticed this evidential success of Russian cinema and that fact was really strange...After that it was clear for me that the director created something really extraordinary film which can provoke different people's feelings and oppinions...So I have watched it ...I was shaken...It was not shock because of unprintable language and constant drinking of main characters...I know, people who have the same life and get into trouble like they did, behave the same way...What was stricken for me is that it was shown spiritual impoverishment of family and society...despite beautiful ostantetious development of Orthodox Church most of comon people who are from former Soviet Union don't have faith in their hearts...that is why main hero lose everything and is not able to find anything which could support him....It's a very true, deep and sad story described by talanted director A.Zvyagensev.
