if I had any complaints it was the animal extermination from the 4th episode became somewhat spurious without any pay off. I imagine it was supposed to show how the Russian public were used and spat out the other side, or perhaps the similarities between what happened and wartime conflicts, but we didn’t get to see much of the effect of what happened outside a single shot of a dead eyed soldier. Maybe that’s all that was needed perhaps.
This is explicitly covered in the podcast for this episode.
There was also some stuff they filmed but left out of the final programme because it was too horrible.

Oh and the soundtrack was suuu-perb. It was just different sounding; haunting and creepy, I don’t know what instruments were used but it felt sort of Bladerunner-esq to me, perhaps? Not the future synth, just, the tone and feel of it? You know what I mean?
The music is covered in some detail in one of the podcasts.
VERY SUBTLE HINT HINT - Listen to the podcasts, they're fantastic companion pieces to the programme.
