It’s a movie, not a book. The audio book is 16 hours runtime. The movie is 2 hours. Some things were always going to be left out. The details of the science stuff was one of them. It works better in a book narrative where the process is told than a movie where it’s visual and you have to show.

The Martian book has more of the science process than PHM book does to begin with.

The movie hit all of the primary points but never got into the details. If you read the book you can fill in the details. I imagine that a lot of people watching the movie didn’t know why some things were happening. Maybe some will be interested enough to read the book or the audiobook. If not, they had a good experience in the movie anyway.

It’s still a really good movie.

What bugs me about the editing in the movie is they gave only a couple of seconds of screen time for key plot elements like the nitrogen resistance breeding and how/why this would cause issues for Rocky. It made the last 20% of the movie less coherent for anyone who hasn’t read the book.
