Now being at the end of the series, I'll say that I still find the older one more satisfying for several reasons. I think the reliance on animation in the new one was a distraction, not an asset, and the other thing that struck me was a sort of defiant attitude that the original lacked. In Dr. Sagan's day it was "look at the wonderful future that science will bring us, and how we got there" and the new one was more "seriously, you pinheads still don't believe in science?"
Whether or not you feel that attitude was necessary is probably the subject for a different forum, so I simply put it out there that there was less childlike wonder and more educated finger-wagging in the new one.
For some of the material covered I would say the same thing about the above in quotation marks. Climate change for one. Anyone with 5 functioning brain cells knows it's happening yet it's still being denied.
