At first I was a bit annoyed with the spectacle-oriented presentations, but as the manufactured drama gave way to direct / diagrammatic graphic representations of various aspects of the topic, I was able to let go of my chagrin (don't really care for "spectacular" science shows / magazines / presentations) and give over to that essential childlike wonder at the incredible implausibility and mystery of that which exists. Excellent series.
The fifth star is earned precisely for that aspect I personally dislike - I hope more people become interested in these and related topics - I hope science and the scientific method become more and more a part of all people's thought processes - especially scientists themselves.
