Parents need to know that characters are in peril and there are a number of tense moments and several deaths, one graphic. Creationists will also be upset by the way the plot develops.

Families can talk about the choices made by the characters, including one who commits suicide to save the lives of others, and about the prospects of space exploration and colonization. And it is worth pointing out to kids who watch today that they are the same age as the characters in the movie, who would have been children back in the year 2000. Point out the brief home movie footage showing two of the characters circa 2000, around 11 years old, and already dreaming of going to Mars, and ask kids what their dreams are, and help them think about what they will need in order to get there.
