Vera Farmiga, 1970s, exorcism and a haunted house, (forget the BS Salem Witchcraft part of the story.) The setting, art direction, characters and performances will please horror movie lightweights, like me: yes.
Positives; the actors, it's French/Belgian, working/lower class, mixed martial arts. Negatives, the narrative shifts from character, to character, the story relies too heavily on the "how messed up do I have to be before you'll love me" device, the script is mediocre, and unforgivably, it's too long. A tepid: yes.
