Starkey has become increasingly difficult to accept as a historian because he is all opinion and sneer without the evidence. Lucy W does tend in that direction too (but I really like her).
I went to a Lucy W talk recently and she said she saw it as her job to be at fluffy end to draw people in and hopefully get them reading more rigorous or academic authors - something like that anyway.
Done her job well with my childen - they all happily watch history documenatries now - and starting to show interest in books on the subject.
David Starkey is a harder watch than many of the others - though like many here I've enjoyed Mary Beard programs.
