The movie seemed to jump around from one genre to another. Sometimes it was historical epic, sometimes it was spy flick, sometimes it was love story, sometimes it was philosophical drama.
As history, it's clear the movie took some license with events to improve the story, and especially that the timeline for events was collapsed. The broad strokes are accurate enough; the struggle between Mary I and Elizabeth over the succession to the throne was real, as was the constant pressure on Elizabeth to choose a marriage with political benefits. I admire the filmmakers for finding a way to make Elizabeth's efforts to create religious compromise interesting as a plot device, and I liked their portrayal of her initial ineptitude as a ruler, taking advice that led to a disastrous invasion of Scotland. On other important points, though, the movie definitely distorts history; there's no evidence Mary of Guise was assassinated, and Robert Dudley most certainly was not involved in a plot to remove Elizabeth from the throne. Dudley apparently remained as one of Elizabeth's favorites for the rest of his life.
