The Vatican's newspaper L'Osservatore Romano praised the movie for highlighting the "sacrifice" needed for good to triumph over evil.
"Certainly, Rowling's vision lacks a reference to transcendence, to a providential design in which people live their personal histories and history itself takes shape," the paper said.
But added that the film and the books make clear "the line of demarcation between one who does good and one who does evil, and it is not difficult for the reader or the viewer to identify with the first.
"This is particularly true in the latest film. They know that doing good is the right thing to do. And they also understand that sometimes this involves hard work and sacrifice."
They gave the movie four stars, which is not only rare, it was quite the compliment for author J.K. Rowling.
