Not fair to rate the acting, as the real people do all the talking; the actors simply walk through the re-enactments. The camerawork is outstanding, and the entire documentary creates a mood that is eerie and suspenseful. The best character by far is the private investigator, Charlie Parker, who seems to be the sole voice of reason and logic. Although I already knew the story and its outcome, I was fascinated by this presentation. Bart Layton is an outstanding director.
