It glosses over the “science-ing the shit out of things,” to use a Weir-ism, favoring the emotional connection , and compacts some other plot points, but everything that must be there is there, and done well. IMHO it’s pretty close to perfect as an adaptation to complement and revisit the book in a dramatic way, but it wouldn’t replace reading it.
For the record, I think project Hail Mary is a much better book than the Martian is, but the two films are roughly equivalent in quality. Damon is a little better than Gosling as the author stand-in, but r the Rocky dynamic makes PHM a more compelling story.
