I'm a librarian who loves anime, manga, and reading a wide variety of genres.
[I put spoiler tags on one bit that I thought might upset those particularly sensitive to spoilers, although I don't think even that bit tells you all that much.]
I finished The Martian a bit later than planned, but the important thing is that I got to the movie with minutes to spare, and tickets weren't sold out.
This was one of those cases where I thought the movie would be better than the book. Sadly, I was wrong. Most of what happened in the movie followed the book pretty closely, but a lot of things were cut out: some of Watney's mishaps and a lot of the science and math explanations. This had the unfortunate effect of making a lot of what Watney did look a lot easier than it was. Growing potatoes on Mars? Just lay out some Martian dirt and plant each potato piece with a glob of human waste mixture and some liquids. Also, I didn't think this was possible, but the characters in the movie were even thinner than the ones in the book.
The biggest changes:
- Venkat Kapoor became Vincent Kapoor. Why?
- Additional drama at the end.(show spoiler)
On the plus side, it was nice to get visuals for everything.
