What a missed opportunity to make it a proper, thoroughly enjoyable watch. The use of photography ruins badly the whole experience with senseless shaky pictures adding nothing to the story. Unfortunately, the editing follows suit. People, in real life, do not shake their heads when they look at something that's why our inner ears balance (vestibular system) was invented in the first place by evolution (or God, depending on your view). It is a pity because it takes so much away from the film. The leads are very good, especially Claire Foy who is by far the most realistic figure in the story. I also think that the death of the three astronauts in 1967 was brutally ignored in the film and the repercussions it might had on the leads.
