This movie is one of my personal favorites, as well as a favorite for my boys. The message is terrific - "you are who you choose to be - YOU decide". Hogarth, the boy, befriends the iron giant, who becomes a very endearing character. The giant is designed to be a weapon, but after seeing Hogarth's "Superman" comics, the giant decides he doesn't want to wield violence. His love for Hogarth leads to his very moving, self-sacrificing decision in the end, and he saves the whole town. I still cry every time I see that scene! The movie does end on a very positive, hopeful, uplifting note, and the audience knows that Hogarth will eventually be reunited with the giant. It is an absolutely terrific movie by Brad Bird, who did "The Incredibles".
