Just finished the book in the last few minutes. Excellent read (thanks Dave and Firewalker for the recommendation).
Looks like it's rated 12A in the UK, so I guess some of the language has been toned down for the movie?
Would like to take my 8 year old if it's safe (not worried about the odd bit of foul language)
Yeah, almost all the bad language in the book is taken out.
We can put a man on Mars, but he's not allowed to swear on the comms back to NASA

It generally remains true to the book, except for generally being shorter and having some scenes stripped down or glossed over, which is what you'd expect with just about any book-to-film adaptation, especially a geeky one.
Love the way he's just cavalier about handling hydrazine inside the hab without any protective clothing - that stuff will get you seven different kinds of dead well before you've extracted enough hydrogen to start a fire/explosion from the hydrogen.
Does this forum software have "spoiler tags"?
It's pretty good
