The legal system shown in the film
Is it really that simple to accuse and put a man behind bars for murder? They talked about evidence and a blunt trauma to the back of the head. Couldn't that have been the result of her jumping into the sea and hitting a rock? What about the hammer as an evidence? Did they find any blood stains or hair or anything whatsoever that could prove that it was used to hurt Lilya?
It seems all the movie and the writer/director wanted to stress upon was the monstrosity and evilness of the system, the mayor and the church. I want some solid proof. Else I cant believe that the system and the state of things could be so unjust in a first world country like Russia.
