The simple fact is, anyone who watches a film and decides to walk away from his/her religion based on that was going to leave it anyhow. This is the same hysteria like we saw prior to the release of the DaVinci Code (which was fiction), Christians could watch the film and not suddenly leave the Faith. Few, if any did.
Seems to me we would all be athiests... if it weren’t for God!
In fact, I’ve heard of a few Catholics return to their faith because the movie (or book) caused them to think about spiritual matters again.
