When The Exorcist was premiered it seems that its impact on believers was so great that people in the audience fainted, run out of the theater screaming, there were ambulances outside to take care of the sick, etc.
This movie doesn't go that far of course, but I imagine that what they call "sensitive audiences" for rating purposes would view this film with awesome respect for what is going on within the story.
I don't believe in anything so, my point of view lets me see this movie from a "naturalistic" perspective, no supernatural phenomena for me.
I rented this movie because I thought Alejandro Amenabar was its director, he isn't, he was one of the producers, but even so, the technical part (photography, color, editing, sound, music, etc.) is absolutely perfect, silky the pacing, a pleasure to the eye and to the ear and the discovery of a new promising name in directing.
The acting impeccable, and good entertainment too. Not bad for the price of a rental fee.
