The clunkingly awful dialogue of The White Queen has a strange hypnotic quality for me. In Shakespeare a couple of minor lords etc. dash through the exposition, and the leading characters then say or do something interesting. In The WQ everything is exposition, but perhaps that is necessary because narrative history is no longer taught (oops, wrong thread!).
If I had been young Henry Tudor I would have grown so fed up with my mother banging on at me about becoming King of England (on very shaky grounds) I would probably have cleared off and done something else.
