You can understand where I’m coming from then since the book felt just a science-y as The Martian movie/book to me. They didn’t exactly cut the science out in Hail Mary, but instead of making it front and center they alluded to it now and then but didn’t fully explain it to the viewer in some cases (to fit in more scenes, I suspect).
Certain details of time dilation and the ship’s gravity device for ex. really help build important tension that was mostly missed in the film.
To me it felt a little rushed though, so I have my fingers double crossed that an extended version would bring it from “good” to “excellent” in my book.
