I am not a great fan of serial killers films, but SE7EN, ZODIAC, SILENCE OF THE LAMBS were outstanding material, even for a non fan as me. I must be fair. This one is perfectly in the mood of such scheme and also the Russian society spirit: dark, hopeless, gloomy, desperate, bleak, brutal. Nothing Hollywood like here, you can also think of some South Korean features such as for instance MEMORIES OF MURDER and many more. I prefer this kind of Russian film instead of pure propaganda war movies or lousy, stupid CGI war costume films...This very flick, I repeat, is the just reflection of the modern Russia. Flawless production design, I would only add that the script is maybe confusing, hard to follow. David Fincher's SE7EN and ZODIAC were a bit easier to get watched. Anyway, it's worth the ride.
