Put me in the "not overly impressed camp" as well. I thought there were way too many scenes with the narrator in them.
I learned something about Bruno I didn't know before. Namely that he existed.
It had a bit of a propaganda feel to it, IMO. Almost felt like they were trying to defend science and the scientific method to a certain extent.
The subtle homage to Sagan was nice.
You don't remember the original one well then. It was heavy on evolution, used Venus as a foil for MMGW and the greenhouse effect, and tied in the KT impactor to nuclear winter and a heavy undercurrent of "ZOMG Reagan is going to kill us all!"
They went to Bruno because they didn't want to re-hash Kepler ,Tycho Brahe, and Galileo.
And because the Kepler telescope, and the earlier gravitational wiggle technique in the early 90's has confirmed several hundred planets since the original series aired, making billions of planets a statistical certainty we didn't have in the 80's.
I think that part of the problem with the Cosmos reboot is that the thunder has since been stolen a million times since by CGI- heavy space and tech shows on cable and PBS.
It's a tough tightrope to walk, agreeing the universe is 12x10^9 years old, and with evolution, and that young earth creationists and ID'ers, are FOS, but still disliking how the secular left uses it to constantly demonize, antagonize, and provoke them at the same time...
