It is difficult to stop it for tomorrow. Acting is high quality for almost all. Some scenes are rather over reacted. The British factual life parsimony makes most scenes believable and realistic. Was the man deep down in doubt of his actions? The screenplay is not clear about what we are to believe related to the man's consciousness. Perhaps this is what makes it even more interesting.
One more play based upon the tragic result between human biology and culture.
We live a life that demands a discipline our biology is constantly challenging. Will we ever as a species acknowledge this contradictory fact and modify our values to make them more easily compatible with our biological essence?
