The Apparition [is a] thoughtful and measured French film that tackles that most unfashionable of subjects – faith. Vincent Lindon, looking even less shaved and more sleep-deprived than usual, is Jacques Mayano, a journalist who’s struggling to get over the loss of a colleague in Syria when he receives a request from the Vatican. A teenage girl [Galatea Bellugi] in the French Alps has become a fawned-on celebrity after apparently experiencing a Marian vision. And what the well-heeled Cardinal he visits wants Jacques to find out is whether she’s a fake. […] Xavier Giannoli’s film moves slowly but with considerable power as it explores faith, doubt, mass hysteria and the desperate human need for supernatural reassurance.
Paul Whitington, Irish Independent
[The Apparition is a] film about the mysterious workings of divine grace, and things that can’t entirely be explained away. It is showily freighted with the music of Monteverdi, Arvo Pärt and Jóhann Jóhannsson. Giannoli’s film-making has its own fluency, seriousness and weight. Like Jacques Audiard, he knows how to get the wide shot and the bigger picture, the panoramic sweep that exalts the immediate emotional drama.
