Coversations
Enjoyed the movie - I knew going in it was at core a teen age love story.
However - One distraction.
The time it would take for communication data to reach Earth from Mars, and vice versa, is at least ten minutes depending on the distance between the two planets at the time.
The distraction is the real time conversations that could not happen. There would be at least a ten minute wait to get a response, not the immediate responses shown in the movie.
