I watched this series as a child of 12 in the 80's and was enthralled at the knowledge and wonder it imparted upon me. It placed in me a fascination for cosmology not because I had any interest in science, but because Sagan answered the questions I had about evolution, atoms and the universe in a way that can only be described as the conversation of a freind. Before Sagan, we were dictated to by the "experts" and may have understood the questions but found it hard to understand the answer. "Cosmos" is a ground-breaking series on the nature of our universe, presented in simple, humanitarian terms. Very little has changed in our knowledge of the cosmos since this series ran, so it is still a valid exploration of our universe. This edition includes "updates" which are, in fact, little more than a nod to new discoveries or recently proved theorums already outlined in the main programme. This series is timeless, and should be shown to every school-child in the world. And, indeed, every adult ignorant of cosmology. Wonderful television. Wonderful subject.
