Neil de Grasse Tyson is hosting a new version of Cosmos, the documentary on the universe originally produced by Carl Sagan (Sundays 9 PM on Fox; Mondays on National Geographic). The first episode was disappointing to me, for two reasons. First, it was excessively simplified. Although Tyson covered many important points about the history of the universe, it was rare that he offered evidence for them. One exception was when he mentioned the background radiation left over from the big bang. The other disappointment was the frequency of commercial interruptions. These were very intrusive, and sometimes deceptively so, such as the ad from Boeing, which had some of the graphic aura of the documentary. There is a simple solution for me, and that is to record the show on my DVR and fast-forward through the commercials next time. Still, it is annoying. I understand that PBS made unacceptable demands for editorial control of the program, but the demands of commercial television do not fit very well with my idea of a documentary. Another feature that some might not like is the use of animated cartoons to depict the story of Giordano Bruno. This was a good topic to tackle, illustrating the negative role of religious dogma. Bruno was a visionary, not a scientist, and he had little evidence to back up his radical views on the infinite character of the universe. From the lens of today, burning at the stake seemed truly an unjust punishment. Tyson is not a polemicist, but this was a hard shot at dogmatism. On balance using a cartoon and not actors and sets to illustrate a straight historical narrative seemed to work. Not everything need be a movie. So I reserve judgment. I am planning to watch the next episode, but I hope it gets into details and evidence and not just fancy graphics embellishing the narrative history. The whole point is to convince people that they should believe the narrative; only the most naïve will accept a bald story.
