I am happy to see that Russian scifi films are finally moving towards the Russian scifi literature that I loved so much as a child. This is a wonderful little gem, a Russian version of Life, but with more focus on the people and less on the special effects and action scenes. Not perfect, mind you, but so far the best Russian science fiction film I've seen them make recently. And the special effects were very good, too, which makes the decision to keep them in the background so much more laudable.
The weakest link is the main character, unfortunately, who does things that make little sense for a scientist. Yet her contribution is not that of a character, but as a carrier of the audience, so what she does is really not that relevant.
I hope Russian cinema will start bringing back the intellectual slow burn story, the civilian scientists that have to solve problems without relying on strength or weapons, but on their own thinking.
