I thought the acting by the main characters were superb, particularly the young boy who played the son of this highly dysfunctional couple. My heart went out to him, his parents behaviour was unbearable to watch as the effect of their toxic relationship was so damaging to him. For me it showed how so called intelligent, middle class people have the capacity to psychologically and emotionally damage a young person’s life. Basically this couple are totally selfish and wrapped up in their own deluded lives. I enjoyed this series although at times it was relentless and hard to watch.
