I have been watching horror films lately, which is a bit of a switch for me. I remember seeing the Exorcist films and even watched the second one again recently, wanting more of the inner life and workings of the priest, Father Merrin. This film far exceeds any I have seen dealing with this subject matter before (Emily Rose being a close second).
You have the usual Hollywood stuff thrown in, but what really gave this film such a high mark for me was the great masculine, spiritually focused portrayal by the main priest as played by Timothy Dalton. His characters friendship with the other priest and his inner life is exactly what I longed for in similar films dealing with exorcism but NEVER found. This is not a perfect film and Dalton does say one famous Betty Davis line that takes you right out of the film (I laughed) but its entertaining and I think riveting. More time could have been spent with the overwrought parents, especially the dad who seemed more possessed than the kid at times, and they didn't spend months working on the child as I think it took in real life, but all in all a good faith effort. Yes, a testimony in part of the fact that Jesus has Won and Wins and that saving souls is still important even in modern times. Rent the DVD and watch the extra (a real life interview with one of the priests involved in the exorcism).
