I enjoyed COSMOS by Carl Sagan at the time it was first broadcast, but since then, I now agree with the professors I had at Cornell who felt that their colleague was very vain and self-aggrandizing. I can't watch it anymore because there's a scene where you are shown the Great Pyramid, Sagan to one side of it and the sun rising. One of the professors I had said that the scuttlebutt around campus was that Sagan thought he was Ra, the Sun god.
I had an encounter with Sagan on campus. I wasn't out to find him, but by mere happenstance he was just in front of me as we were both walking through a campus parking lot. All I wanted to do was to say hello. He noticed me, looked like a scared rabbit, dashed and darted to his VW Rabbit (yes, it was, and a convertable to boot) and drove right past me, looked at, but never acknowledged me in any way. I felt that I had "intruded" on his "space" (no pun intended) as he left the Space Sciences building. I've had a mixed feeling about him ever since. I mean all he had to do was wave back.
