I'm up to episode 4 I think. Emma Corrin is perfect for the role. I'm disappointed that we don't see more nuance in the other characters, as we did in the other series. Olivia Colman is excellent, but wasted, I think. Many of the characters are shown only in how they relate to Diana. What is Princess Margaret doing, for example, other than sitting in Buckingham Palace; what about her private life. How is the Queen relating to Phillip? We don't really know.
