When I interviewed the founder of the Act One screenwriting program, Barbara Nicolosi, a few years ago, she told me that one of the primary storytelling principles they teach their students is, "It isn't telling people the truth that saves them; it's getting them to wrestle with the truth that saves them." In other words, it's telling the story in such a way that the ideas that are presented don't just go in one ear and out the other, but that they're internalized in a way that makes them real to viewers and can possibly have an effect on their lives.
Though I don't know how it all ends, The Confession has the potential to be that kind of story—to make people wrestle with moral and spiritual questions in a way that stay with them long after the final scene has faded to black.
(Due to intense violence and language, The Confession is intended for mature audiences.)
