At the conclusion of Hollywood disaster movies and epics, time moves backward, piecing together like a jigsaw the elements that had come apart. The Titanic resumes its journey; Russell Crowe is reunited with his murdered wife and son. It's not a happy ending; it's a convention created for the purposes of an impossible sense of uplift at the end of death and tragedy: the happy beginning. Technology makes Hades unnecessary.
