- Science is in the spotlight. Problem solving, in particular, and that's what ultimately keeps the hero alive. It's something we should see more often in movies... it's not about who's the strongest or the luckiest or the fastest ...
- Teamwork is also emphasized in the film. The hero may be alone on a distant planet, but our entire world is behind him.
- The Martian landscapes are beautiful. They emphasize the wild beauty of Mars. Congratulations for including craters in the Southwestern style landscape, dust devils and a Phobos growing in the sky several times.
- NASA is not the bad guy. In many space films, NASA is presented as a cold, insensitive entity that simply wants to cover things or make things difficult. In the film, we see the many divisions of NASA that have to work together to solve a serious problem. Being an astronaut is not easy, but it's not easy to be NASA either.
- The film quickly crosses many of the scientific sections of the book, and completely forgets others. This helps to keep the movie entertaining for a wider audience while keeping the recording time reasonable.
- There are some scientific details not quite right on Mars in the movie. The most notable is the representation of Martian storms ... with only 1% of the atmospheric density on Earth, a dust storm on Mars might look scary and make a big mess, but you would not be blown off. Lightning could however be a problem, generated by loads between fine grains of Martian sand and you could potentially catch a fatal shock or lose sensitive electronic components. Oddly enough, the thin atmosphere of Mars is evoked towards the end of the film, but apparently ignored at other times.
- It can be as cold as -150°C (-238°F) during Martian winters and this has clearly not been factored.
- The sound on Mars, although not zero as in space, would disappear after only a few meters from the source ... small noises like the snoring of the vehicle or the slamming of a fallen solar panel would be imperceptible by the human ears after a short distance.
- Lack of sense of the long-term durability of the Hermes crew as they traveled to Earth and returned to Mars, a journey of nearly two years. Whenever you see them, they give the impression of leaving home or at least leaving the previous scene.
Anyway, go see the movie! It's a wonderful and refreshing film!
