Good, although I hope that its a little more coherent than their original attempt. Which I defended it at the time, but it had flaws that could definitely be worked out. In comparison, Bill Nye's Netflix show (which I felt was flawed quite a bit as well) was more focused, while Cosmos kinda meandered (between NDT sitting in imaginary spaceship, animated segments, and other stuff), which I think causes them to lose effectiveness in transmitting ideas. And yes, I realize Sagan's show was similar in having re-enactments and mixing other random clips, and I think its frankly overrated (hell it puts me to sleep everytime I watch it just because its like a droning monotone most of the time). Sagan could be great at getting ideas across, but I don't feel his show was as effective, which is disappointing since you'd think him being able to setup more elaborate means of explaining things would be better, but it was like he just used it to choose random places to shoot short clips (that often didn't have anything to do with where he was shooting the video at, or if it did it was minor), and then the elaborate (but still lacking) re-enactments.
I recall someone at the time pointing out how there's quite a few others (think they linked some other British cosmologist that did a video), that were capable of delving into even headier concepts, but because they presented it in a better way, made it more accessible and did a much better job of actually imparting knowledge.
Cosmos just seems a bit too abstract, especially for reaching younger audiences. And some of their parables weren't entirely apt for their point or were even wrong (I recall that being a common criticism).
