Interesting.
The inclusion of Diane Purkiss is a negative as she is primarily a writer whose interest in history is as a militant feminist. She has stated that witches were invented in order to prevent women, all witches were women, being seen as having any intelligence.
In one book she actually states that the stories of witches being burned in between 1430 and 1730 were invented and inflated to give modern witches their own Holocaust!
As a feminist she is rightly praised, as an historian of witchcraft she is a joke.
The programme, as a documentary on the Pendle Witches and their trial and execution, is fine, anything said about witches therein is, at best, ill-informed and horrendously out-dated.
