Of course you would expect fantastic visuals in 2014, and the CGI effects are definitely first-rate. I also like the simple animation style used for historical segments. I think Tyson is actually a better host and narrator than Sagan - he comes across as confident and authoritative, yet approachable and down to earth, and he's clearly comfortable on camera. But what really impresses me is the writing, especially the way that it humanizes science and scientists. Scientists are not perfect people, and science is not just a bunch of complicated facts and figures. Scientists are human beings who have retained and cultivated the curiosity of children. Science is an often messy process that builds on its past successes but is not afraid to discard what was accepted in the past in favor of new ideas that better fit the facts. It is based on evidence.
In tonight's episode, I really liked the way they portrayed Newton as a flawed and even petty person who happened to be a genius - except when he wasn't, as in his lifelong pursuit of alchemy and Biblical numerology. We are indeed fortunate that Edmund Halley (no slouch in the brains and energy departments himself) was able to recognize Newton's genius, and to encourage and advocate for him (even to the point of publishing the first edition of Newton's groundbreaking Principia at his own expense). Halley's use of Newton's new mechanics to correctly predict the return of the comet that bears his name was a great ending, handled in a nicely emotional and dramatic way. I also liked Neil's comment, "if you're watching this in 2061, you'll certainly know that Mr. Halley's comet is back again."
Along the way, Neil explained a bit about gravity, planetary motion, and comets, with some excellent visualizations. I think it's important that they get the science right, but that they also make it a great story with characters you can care about. They might not cover as many topics as some science fans might like, but I think they have a better chance of engaging younger viewers who might not care all that much about "science stuff" (yet!).
I'm really looking forward to the rest of the series, and to the release of a Blu-Ray edition with lots of cool extras before too long. I hope that young people do find it engaging, and that some of them will be inspired to study and pursue science, as many young scientists around today were inspired by Sagan's original Cosmos in 1980.
