This is a movie that lingered in my thoughts long after viewing. An intricate depiction of psychologically damaged individuals skirting madness and damnation in desperate attempt to magically achieve the unattainable. The presentation, writing, performances, direction, pacing, cinematography, are all exquisite. This is a gorgeously filmed movie that takes restraint and discipline in each and every frame of its slow-burn atmospheric setup. Some will be turned off by the deliberately slow pace and lack of action, but this is a psychologically taut examination of a spiritual journey and trials. As one with more than a passing interest in the occult, I appreciated the attention paid to the rite and ritual, setup, description and methods depicted along with the mental, physical and metaphysical aftermath. When the creeps and horrors begin, they are genuinely creepy and horrifying. A single scene involving shadows and whispers I found far more disquieting than any other I have seen this year. The ending will be divisive and some might decry the climax, but I personally felt it was earned, justified and a fitting coda to the character's harsh journey. If you have the patience and intelligence for slow, almost art-house horror sparse on scares but thick in amazing atmosphere, tension and themes this film should not be missed.
