Visually excellent and top entertainment, certainly not a documentary. Like many BBC so-called documentaries, this has ridiculously pompous sweeping emotive music ( I thought it was silent in space?) which ruins it for me. It purports to show footage from all the probes, but it's nearly all CGI, which is OK up to a point, apart from when we see a probe sweeping across Jupiter filmed by a non-existent companion probe, that just happens to be there with a camera. Please, just indicate what is original footage and what is CGI, with maybe a small symbol in one corner. Is that too much to ask for? And as an academic Cox knows about the importance of, and difference between, first and secondary sources, video included. Nobody seems to care any more. But lots of interesting stuff if you simply lie back, turn off your critical faculties, and give in to the lush experience.
