The Iron Giant and Firefly are both about heroes. Granted, they take a different approach to it, and the crew of the Serenity might actually approach that backwards at times, but Cap’n Mal, Jayne, et all, have good at the heart of what they do. The Iron Giant has that too. He might have forgotten that he’s basically a massive weapon of complete destruction with unimaginable powers, but Hogarth taught him to aspire to be good, to be the Hero, Superman instead of Atomo. But enough with the lecture. They’re heroes, okay?. Big Damn Heroes.
