I just watched Cosmos, hour #1, on free Hulu. As expected, the attraction was special effects, not information, since I am well-versed on that. I disliked 3 things: 1) He travels in an oval spacecraft, a constant distraction from the great view behind him I'm trying to see, 2) the cartoon portions are low-quality and not up to the standard of the special effects, and 3) the unimaginative, superficial calendar portion wastes an opportunity to show evolution of both physical universe and then life.
The show copies the Sagan version in most ways, including the host standing on a deck and looking down on stars, which I disliked in the late 70s and still do. One change is that this host doesn't look up all the time with a Hollywood toothy smile. The original Cosmos was America's answer to the vastly more interesting British series Connections, starring James Burke, which I used to say was my favorite TV series of all time. I suppose it still is. You really should see it if you like science history.
