Technically a Sci-Fi movie, this movie is really a story of a father redeeming his relationship with a son he never knew, and of the character change that occurs in the father throughout the movie. The story is very well told, drawing you into the characters experiences, and although my wife loathes Sci-Fi movies, she loved this movie and cried during some scenes. It's got a lot action in it as well and is fun to watch. I do not watch many movies twice, but I'll be buying this movie and we'll be enjoying it repeatedly. The robot they prepare together serves as a device for a David and Goliath storyline as well. Hard to believe when reading this, but you'll be cheering for the father and son and their robot as well.
