The devil without details Just like when you go to a vampire movie you implicitly accept all the features of the vampire universe (garlic, mirrors, crucifix and so on), when you decide to watch a movie like The Pope's Exorcist you agree to suspend your disbelief in the Devil during two hours.
The opening scene where the Devil is removed from young Enzo is well crafted. By the way, Crowe is a splendid father Amorth. Things deteriorate immediately after, because neither the American family in Castille nor the environment of the abbey seem credible for the purpose of frightening you. You start to understand the weakness of the plot when the only scaring element during the first 40 minutes or so is a set of arbitrary sounds which belong to the soundtrack only, without connection with what should be happening (and is not). Then the devil enters poor Henry and starts a dispute with Amorth, apparently because he knows a lot about his past. Some grotesque (not the same as scaring) scenes are on the way.
The problem (in my view) is that the main characters (Julia, Esquibel, Henry) seem too artificial, and the script does not help them. I watched the film in a cinema that allows an intermission by half of the run time. I suddenly noticed that, given the way things were going after one hour of projection, I absolutely could not care less about the fate of all the characters, Devil included, and I left the theater with a sense of relief.
