I thought that this documentary was a truly wonderful introduction to the Apollo moon landings, showing the human side of the experience and providing a great general overview of the achievements. I saw it on the movie screen, and I highly recommend it.
I also really liked the impressive book of the same title, by C. Burgess and F. French, that not only covers the early Apollo flights, but also delves into the preceding flights, and what the Russian rivals were up to at that time. In the book, I learned about the early lives and early flights of these astronauts, and what it was like to be in the moment of flying the missions. In the movie, I learned what these guys look like today, and how they feel reflecting back on their experiences. Both film and book were perfect for their medium, and great accompaniments to each other.
I highly recommend both book and movie, and suggest experiencing both!
