I caught Civilzation in one of its early re-broadasts, though was too young to appreciate it at the time. I've downloaded it and it's on my watch list.
Note though: the programs almost always had some point of view. Burke editorializes a few times in Connections (particularly in the 1st, 2nd, and final episodes). Clarke has a distinct vision of Western Civilization. Carl Sagan's thoughts on the importance of science, possiblities of extraterrestrial life, and against mysticism and nonscientific thinking are clear in Cosmos. The fact that the views are more aligned with convention don't lessen this any.
