Completely agreed. It's an astonishing film. One of these days, I might write an article about the preview screening I attended (which was for church leaders, but I attended in a journalistic capacity). Half way through the film, the lights came up and one of the audience had to be taken away on a stretcher, because he'd had a heart attack! The lights went down and the film resumed, leaving the rest of us to wonder if we'd make it through the film alive. Quite an experience, to put it mildly.
