I never said that it was the same, just that more would have to be cut than The Martian as the book was much longer, and gave an example of the most similarly wide sci fi novel on my shelf that's successfully been turned into a movie. You're the one that made the leap that the thickness of a book is a definitive measure of anything and wanted the comparisons to be apples-to-apples, which it never was as one book's becoming one movie, whereas the other became two.
