Indeed, to the science savvy viewer, this one has more scientific problems than most films of this genre. And there are many, as pointed out by many.However, this is a fun and entertaining film. Yeah, most of us know that Mars is ~140M miles away and that it takes six months to get there. And that real time communication is just not yet possible. But the launch sequences and subsequent journey to orbit are fun to watch. Almost as good as the launch sequence in Apollo 13. And for the love of all that is holy, a note to all science fiction writers: There is no such thing as zero gravity. Anywhere in the universe. So, put your scientific knowledge in the closet for this one, and sit back and enjoy the ride.

Not everyone can see that and they think is about sci-fi but is actually an romance. Good for who wants see something lovely with a little touch of science. Dont be stupid thinking it was a big film about science and you are not an astronaut not even a scientist.

Shot like a Disney movie, felt like it throughout the movie. The kid and the father just did not mix well for me made for bad acting by both.

Touching story, beautifully delivered. Love that he kept asking, "what is your favorite thing about earth?"
