I have been we CBD for over 20 years and never been disappointed until now.My disappointment was immense. This series is true in content but however it was filmed over half a century ago and has not been updated. The quality is poor and uninteresting in color and format. It could not keep my attention and I will not give them as a gift to grandkids that this was intended for. The price was too much for the poor quality of the product. Like I said, the content of the information is true but needs serious updating. The sections on space travel, astronomy, etc, are oh, so far behind in time and material. Buyer beware. I understand that CBD is not responsible for the content and they only sell the product so I cannot blame CBD...But Moody...well they can and should do better that to sell this low a quality of film. Very, very disappointed that I paid over $100 for this.
