The book, like in almost all cases, is so much better than then the movie.

Eg: she doesn’t travel alone. Think about what that does to the plot.

Ooooh it’s one of my favorite movies I’m surprised I never realized there is a book! Actually I probably knew at some point that there was a book but it didn’t occur to me it would be better than the movie!

Usually the movie feels worse if you have read the book already. Imagination is so much better than movie

Yah I read The Martian before seeing the movie and found the movie left so much out! Makes sense as the audiobook is 10 hours and the movie is 2.

but by going alone, it adds that much more tension/suspicion on if it actually happened. it's easier to believe if more people go and have the same experience. unless it's the Sphere where they all just agree on the idea.
