Not a bad documentary but showing how long ago this was, as we now are seeing the sons of some of the astronauts, rather than the astronauts themselves. The material has been covered in many other documentaries over the years, my favourite remains from the Earth to the Moon. Although did find the narration a little odd, it's Mark Strong, an English actor, for some reason doing an American accent. If they wanted an American accent there are any number of good Americans who could have done this or just have Strong do it in his own English accent, I just found Strong doing a fake accent distracting and annoying.
