There is only one surprise in “A Christmas Prince: The Royal Baby,” and I don’t intend to spoil it. That leaves you no choice but to watch it, but be warned: It isn’t for everyone.
A flimsy fairy-tale from John Schultz, set in a picturesque — and imaginary — snow-spangled kingdom, “The Royal Baby” comes just as the newest generation is toddling around England. The movie monarchy of tiny, vaguely European Aldovia is nearly as old as Britain’s, but far less engaging.
As Christmas approaches, so does an anniversary, that of an ancient treaty with another peculiar kingdom, Penglia. This treaty is renewed every century, with a deadline that falls inconveniently on Christmas Eve, not long before a baby is due in the palace.
