I went to see the film of the book, and thought it was excellent (as expected). Like the book, it was funny, intelligent and gave a good (if not always completely accurate) scientific background to the adventure. It left a few things out, but it was clear that they were dropped to keep things going, and didn't harm the story in any way. The film was also very moving; emotion is where it surpassed the book.

A positive, exciting and ultimately uplifting story. At some point, we have to get off this planet, so I say: let's go to Mars!.
