I'm not sure people in this forum are mostly the intended audience, at least for the first episode. I certainly didn't learn anything I didn't know before; but I'm sure there were plenty of children and people who slept through science class and never read a science magazine who did.
Still, if you like Neil DeGrasse Tyson, or you want to go nostalgic for the original (which was dated by the time I saw it, while this is fresh), it's worth the time.
