Great documentary about a fascinating subject. Program has many interviews with experts on the topic and is well researched. My problem is with the wooden narration. It is obvious the narrator is reading from a script and it is sleep inducing! Narration should be redone. the mechanical Lady on my cell phone has more energy than this Lady and it brings the whole show down a bit. I have never appreciate the skill that goes into narration until seeing this program. I had to put the show on pause and make a pot of coffee just to avoid dozing off. Really guys, all that great work deserves a professional narration. Looking forward to more from this production team in the future.
