I'm glad you said that - that was my take on it as well. I was getting slightly worried that I was watching something which should have been great about spaceflight but I was distinctly take it or leave it! I couldn't work out what I didn't like about it, aside from seeming overly dramatised and not enough actual spaceflight related stuff.
Oddly enough, my wife loved it and it was her who kept suggesting watching more. I've taken this as an opportunity to point her towards the book, the film is lined up next and then we can move onto From the Earth to the Moon
