Just got back from seeing The Martian with
jvowles. Excellent adaptation of the book. Some changes at the very climax due to Rule of Drama with astronauts doing very stupid non-astronaut things, but much of the book was preserved, especially the funnier lines (including cleverly edited versions of Mark's many, many "fucks" to keep it PG-13)
Overall very clever and celebratory of NASA in it's Can Do mode when overcoming multiple problems. Excellent film.
