This video series covers all the basic ideas of cosmology in an interesting and easy to understand manner, with a strong historical focus. The narration, describing this, is very interesting and well thought out. However, the visual aspect is appalling. Most of it consists of out of fucus shots of things that have nothing to do with the program, irrelvant images of star fields, shots of people walking around, shots of empty rooms and other irrelevances. When people are interviewed, they are often shown in very dim surroundings, making their faces hard to see. All in all, the visual elements are just hopeless and add nothing to the video. Towards the end, I didn't even bother looking at the screen but just listened to the audio. I lost nothing by doing this. All in all, Professor Hawking might as well have written another book.
