Yeah I never understand the tiny portion of people that hate on Tyson, he didn't kill off Pluto on purpose after all. It might not be fair to compare him to Sagan or Hawking, but Tyson is a good voice to help represent the idea of curiosity and free exchange of ideas, and he has been for years, seems some people would rather read a dissertation than have a silky voiced super dork tell it to them.
I liked the show though, the Bruno segment was a little long, but I understand what it was for, and why it was there, I actually think it's brilliant, just like airing the show on Fox and 9 other channels and making it one of the most easily accessible things on the web from a major corporation. They're ramming science down the throats of people who don't like it, and then those people are going to run and hide no matter what. But the unsure people, the uninformed/lazy, the children of the closed minded and unquestioning... they'll already have had the seed of curiosity planted in their mind, and it's not arguing against what they've been raised to think all their lives, they can see a faithful person believing in greater things than what are preached in one or two books, and now they might know where to look for some more information about it. and THAT, is where they want people to be, hungry for more knowledge. Just like Sagan did 30 years ago.
