A film with more than the usual spoiler issues. Talking about it in any detail feels akin to handing you a gift-wrapped present and saying, "I hope you like it -- It's a thriller about a diabolical secret experiment."

This is a must-see and one of the best documentaries - and films - of this year.

Although I seem to have had higher expectations than I thought, the movie is super entertaining.

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.

Most interesting thing, during shooting, Tagawa became Orthodox Christian. He is baptized in Russian Orthodox Church.

The movie is done to the point. It has quite a few impressive details and connotations, which probably will go unnoticed to the regular viewer at first sight. Like a flash of lightning behind Nelyubin. Or Nikolay's refusal to fight off the two policemen. Or the hunter's inability to shoot the bear. Or the glance in the water. Or the ending scene fading into white. It can be quite a considerable list of such happenings. No surprise, though, while a real Orthodox priest takes part in this one.A very good example of Russian cinema. Still, one complaint from my side: the music (especially at the very end) should have been different. But this is my taste - would prefer mild choir music in this instance or even just the sounds of nature (birds singing for example). Grebenshchikov's score was great in the famous and groovy "Black Rose...", but not here. Here it sounds cheap, sorry.Thank you for attention. A 9 out of 10.
