I love spy films and tv series. I have seen and enjoyed so many of them. I know the true story of this series and have seen Breach the film previously made based on the story.

Being such a spy fan I loved all the details in this. It was well written and well acted. I loved seeing all the British actors in this,I am British. The drama shows the evil of the USSR,and some people still defend its memory?

But I can see why some people would not like it and can see why it was cancelled. It is detailed and talky and there is little action or exotic locations. But if you are a spy person you need to see this.
