Very much watching, and I like it a lot! Tyson isn't as engaging as Sagan was; in the original Cosmos, you find yourself very quickly getting used to Carl's style of talking and he draws you in to the adventure.
Neil is a little more aggressive in style, but it in no way diminishes the quality of the production or how great the solid statement of science and the use of the scientific method to determine truth.
I do sort of miss Vangelis' Heaven and Hell score a bit, though. :)
