The film is strong on the ruthless politicking in which the likes of the more or less guile-less Jane were caught up. However, it does go on a bit, and there is much that is fanciful. The deep intense relationship between Jane and Guildford has not the slightest historical foundation, and neither does their utopian plan to improve the lot of the poor and make everything harmonious in the kingdom.
It's a good story, only weakened in my view by the intrusion of somebody's overactive imagination. I don't think the film does justice to its subject.
