This is another title that falls in the category of overrated TV series. I do believe they put a lot of effort into trying to follow the timeline that happened in real life and I do believe they managed to do so quite subtly. The first two episodes and the last one did deliver, but they should be treated as episodes from a documentary movie mixed with and artistic TV series. Unfortunately episodes three and four are a true letdown or "meltdown" to cite the characters and they seemed dragged out and forced. We should not take this TV series for a full artistic one, therefore we should not expect a lot of character development, but the main leads did really well from my point of view both Boris Shcherbina and Valery, yet we should not forget the fictional character played by Emily Watson. This TV series highlights that sometimes in order to survive you do need to have the luck on your side.
