The first time I saw this movie, I was affected for days, even though I am a lifelong follower of Christ. The second time I saw the movie, I rose to my feet at the beginning and stood through the entire showing (at the back of the theater). Since then, I have seen it many times but I will never again sit through this movie - knees or feet, but never sit.
When I saw the movie in the theater (which was packed), when the movie ended and the closing credits were on the screen you could have heard a pin drop in that theater as people were leaving. They were just stunned silent, as was I. Many had tears streaming down their faces. It was VERY powerful.
