Definately read the book, also the audible audiobook narrated by R.C.Bray is totally worth a listen too.

Something to note is that there is a ton of stuff that the screenwriter missed that created plot holes & scientific absurdities in the screenplay, that if I had not read the book 1st would have made the movie unwatchable.

Marks story in the book is also way more thrilling as the author throws a ton more things at him which need the shit scienced out of them.

BTW IMO there is only one humorous point in the written word that does not come through in the audiobook or movie. When Mark is told that he should watch his language as the world is trading his words he types I think:

>![12:15] WATNEY: Look! A pair of boobs! -> ( . Y . )!<
