first thing first, Father Amorth is the coolest exorcist one can ever see in the movies or ott. I liked the way, he was so much invested in science and psychology and believed that more than half of the cases just needed some Psychiatrist help. Though at the same times he also believed in god and devil.
horror was fine fine in the movie, I certainly didn't like the acting of character Amy a.k.a Laurel Marsden. Most of the time, it looked she is over-acting. her scenes were big off to me. But again these are my thoughts only. She is definitely good actor, I just dont know why she doesnt seem that good actor in few scenes here. All the characters have played their part well. definitely one time watch.
