Probably the only thing necessary to keep your crap detectors up and scanning for, will be anti-religion bias, and shots at Catholicism, though subtle. A good friend of mine informs me that the show will continue to spread the myth that Giordano Bruno was burnt at the stake by the Church because he postulated that there were likely many inhabited worlds in the universe. This is a clever way to mock the mediaeval Church, but it is historically inaccurate, simplistic, and manipulative. As a Catholic and a Science Teacher with a PhD in the History of Science and Technology, I've had to listen to such anti-Church prejudice out of these guys for a lifetime... but they have an agenda.
But enjoy the actual science in there, I'm sure that they have even more money to work with than my old buddy Carl, and he did wonders with his budget. But even Carl indicated to me that the reason that he went atheist was his disgust with the Church doing things like destroying the Alexandrian library [only marginally true, and then still Dark Ages times] and the Bruno affair.
Science IS good and fun... but only as long as the scientists talk science and get out of areas where they know less than you or I.
