I think that she does her best on making a villain interesting. I agree that her performance on series 3 was kind of stereotypical, but we don't know if it was her intention or if it was the director's command, since Nathaniel acted about the same way in the last episodes of series 4. Even if it was Katie's acting, I think we must forgive this to her since it has been her first time portraying a villain. Also, you have to admit, in series 4 she improved greatly! The smirking stopped and she added quite a lot of depth to the character.
