I like it, but not historically accurate
The prologue states that everything in this film is taken from historical records. If that is the case, they shouldn't have included a romantic interest between Bernadette and Antoine. He was already married when her visions began and their friendship was platonic. The idea that he was in love with her was taken out of Werfel's novel as was the business about her running ahead with the wood, and staying in the widow's house. The widow did believe Bernadette, and did at first think that the lady might be her dead daughter (such things were not unheard of, it's called a revenant and is harmless) but she did not have Bernadette staying in her house and wearing her daughter's Children of Mary outfit. They have also got the fictional character of Hyacinthe de Lafite in the freethinkers' cafe. No such person existed. He was invented by Werfel, as were a number of other incidents in this film and some of the dialogue.
The whole scene where Antoine runs to the grotto and rallies the people to rescue her from the police interrogation was just plain embarrassing.
They should have used the biography by Trochu. The facts have been so mixed up with Werfel's legend that I doubted a movie about Bernadette that sticks to the facts could ever be made until I saw "It is enough to love", a French film which was made in the 1950s. Although it kind of compresses things for time, it's tons more accurate than either this or the Selznick film.
What I like about this film... it's understated, they're being very careful about period costumes and manners. they're singing local and period hymns, and the background music's a lot better. I love the old Song of Bernadette, but the music is too exaggerated and churchy. The way I understand it, the whole experience was very understated and much more like it's portrayed here.
