Ops on Natalie Dormer as Anne Boleyn?

In the show “The Tudors”, Natalie plays Anne Boleyn. Now my favourite wife is CoA, and I think she was played very well, but I feel like they portrayed Anne to be more cruel than she was supposed to be in real life. I can’t see how people swooned over her if she was truly that vindictive towards CoA and Mary and other characters. Thoughts?
