As a skeptical person, the preachy tone of the movie kind of annoys me, not enough to make me stop, but it does make me have a more biased opinion about such religious thriller/suspense. In one hand I found the scary scenes really boring and in no way scary, in the other hand, the point that if a person lives a life of mainly hedonistic pleasures won't find happiness is something I believe as well. While I'm not the norm, one doesn't need to be religious to avoid alcoholic beverages, the use of heavy drugs and other hedonistic pleasures.

That said, the part where one doesn't need the church to be religious was actually a nice message. One does not need an institutionalized religion/church to be religious and/or spiritual. Being an agnostic atheist doesn't make one already a hater of religion in itself (especially since I also take some of its teachings - and from other religions - to heart) but it does make me wary of such organized religious groups like the Catholic Church, or cults like the Church of Scientology.

Regardless of such ideological and moralistic debate, this movie didn't age well, especially if you identify yourself as an atheist, agnostic or whatever definition based on skepticism and rationality to heart. Hell, I don't think that even a religious person would like this movie that much, regardless of its position of organized religion.
