I did a bit of research after watching it- never realised Millais was responsible for a lot of the paintings he did. I love looking at art - National Portrait Gallery one of my favourite places on the planet, but admit to knowing very little about it. Ruskin was 'different'- very surprising in a way that he had a career at all but obviously of his time.
Thought the cast generally bore a lot of resemblance to the real life people they were portraying looking at pictures of the main protagonists.
