This movie is as much a cloak and dagger story as a Christmas Romance, perhaps even more so. The suspense of a plot against the royal family runs throughout the movie with the climax being focused entirely on that. There are clues and red herrings sprinkled into the story.
I was surprised to see Rachel Skarsten as the lead, Claire, because I almost didn't recognize her. I was totally impressed with her in Marry Me at Christmas and her performance here shows a different side of her, although both characters have a reserved personality. Skarsten establishes a good working relationship with all the major actors playing characters in the royal family including Dan Jeannotte as Prince Colin.
Given that to all appearance, this Royal story is set in a country we know to be real, it was distracting to me trying to keep putting down that nagging demand for some reality check especially regarding romance between an orphan and a Prince. I kept thinking "No way", but any viewer already knows that such expectations don't apply in this kind of movie. Most Royal stories are set in a way that the prince or princess is not from a real country.
In the beginning there are several practical jokes attempted both against Claire and even by Claire which help create a light heartedness in the atmosphere. (I am irritated once again by network previews showing a little too much, not in terms of spoiling the plot, but taking the impact out of at least one of the funnier scenes.) Getting deeper into the movie, the tone moves more to the sentimental as Claire bonds with the family, especially the children. I already mentioned the cloak and dagger suspense.
