Christopher Eccleston in my opinion is one of our finest actors. He is in very good company in this mini series as the acting from the rest of the cast is superb. The children are utterly brilliant as is Paula Malcomson. It is such a raw and tragic story of the collapse of a relationship and a marriage. It shows how things can escalate by making a few bad decisions. The brilliance here is it shows faults on both sides. It also shows the impact a break up has on the children really well. I binged watched it in one sitting. It stayed with me for days after. The BBC are really the best at mini dramas.
