Meh.

All characters are 1 dimensional and completely interchangeable. Emotion is never explored at all, somehow Mark makes jokes and is logical no matter the circumstance.

The author feels like a new author to me; Weird writing style mixtures. The book starts out with mark getting wounded and isn’t ever mentioned again even though he’s permanently doing physical labour. Plot suspension is built over some time and after things are avoided, it’s never mentioned again by anyone, not even the fact that things were avoided.
It feels like it was based on the movie, but somehow with less emotion than cinema.

The book ruined the movie for me, and also the book.

The science was really cool though!
