Having read the book, I believe they came very close to nailing it as a film. They didn't inject crap that was not in the book, they didn't expound on anything with unnecessary character traits or motivations. Yeah, they could not be quite as detailed in the film due to cinematic pacing reasons.
Casting was top notch - when I was reading the book, I was picturing a woman very much like the actress portraying Stratt due to Weir's description of her.
The film's design elements were excellent. I have seen some comparisons to Alien, but I'll disagree with that one. Alien was far more beaten down, used, and industrial to be a fair comparison. No, this one made me think of 2010. The well-lit controls in the cockpit looked quite a bit like the look of the bridge of the Leonov in 2010. While they didn't specifically focus on it, they had the same spinning technology present in 2001/2010 to generate artificial gravity.
But where I believe the movie dropped the ball is in the score. There were some good choices made for source music, but in terms of the actual composed score, I can't say that I even really noticed it. I look at movie scores as the emotional connective tissue between story and visuals. This score simply did not hook me into the movie as it should have. I know I'm making an unfair comparison (I have never heard of the composer, and film music makes up the majority of my music library), but think of Zimmer's music for Interstellar. Like PHM, Interstellar was at its base an emotional, human story that was augmented by the score. John Williams frequently wrote scores that told stories. So yeah, comparing this composer to two of the very bests to ever write film music is incredibly unfair. Maybe upon a second viewing, I'll get more out of the score, but with this one viewing, I just didn't feel like the score worked.
