[[caption-width-right:350:The usual reaction to this movie.]]
!!Movie
* Watching the Giant struggle in pain as the electrical wires he had been trying to eat at the power plant electrocute him. It's the first indication that this isn't just a monster, but a sentient being with feelings, which is why Hogarth goes back to save it.
* Literally the entire scene once the air raid siren starts going off. Starting with Hogarth [[ExplainExplainOhCrap explaining to the Giant what it means.]]
-->'''Hogarth:''' [[spoiler:A missile! When it comes down... ''[crushing realization]'' ...everyone will die.]]
** This exchange of dialogue. Just the hopelessness and sense of realism in Dean's voice:
--> [[spoiler:'''Annie:''' Shouldn't we get to a shelter?]]
--> [[spoiler:'''Dean:''' ...it wouldn't matter...]]
** [[spoiler: [[http://www.youtube.com/watch?v=D4dT2eBWI2M The Giant's]] HeroicSacrifice]]: "[[MeaningfulEcho You...stay. I...go. No following.]]"
** "''[[ItMakesSenseInContext Superman...]]''" Who knew that Creator/VinDiesel could reduce grown men to tears with a single word? [[ComicBook/{{Superman}} Kal-El]] himself would be honored.
** The way Hogarth whispers "I love you," as The Giant takes off.
** Hogarth tearfully clinging to the Giant's finger as he pulls it away.
** The utter ''exhaustion'' in General Rogard's voice after the giant's sacrifice is tear-jerking in its own way as well.
*** General Rogard figured a huge irony out of all this, he realized that the Giant that they were deployed in fighting against was the hero that stopped the missile from destroying them all and it was indirectly ''his'' fault.
** And hell, just the realization that the Giant takes Hogarth up on his advice of proving to the town that he's good... [[spoiler:by ''sacrificing himself.'' Feasibly, he could've shot the bomb down, but no, he chose to do this so he'd never bring all this chaos to anyone again.]] [[WoobieDestroyerOfWorlds Oh, Giant.]]
* "Souls don't die..."
* The Giant after [[spoiler: believing Hogarth to be dead. Even savvy viewers that knew otherwise got choked up by the Giant grieving for his friend.]] Especially when he starts trembling and buries his face in his hands.
** If you listen close during that scene, you can hear the Giant whimper, "Hogarth."
** The way [[PleaseWakeUp he nudges]] [[spoiler:[[PleaseWakeUp his unresponsive body]],]] [[MeaningfulEcho just like the deer]], and starts crying as he puts two and two together.
** Watching the Giant [[spoiler: succumb to his defense mechanism that he so desperately wants to defy, especially after almost killing Hogarth with it]]. It's both tragic and horrifying to see this GentleGiant [[spoiler:suddenly turn into the monster he doesn't want to be]].
** [[MyGodWhatHaveIDone The Giant hyperventilating like a frightened child]] once he [[spoiler:snaps out of his rage and goes back to normal]].
* The deer in the forest and Hogarth's explanation of the concept of death to the Giant.
-->'''Hogarth:''' Things die... It's a part of life. It's bad to kill. But it's not bad to die.
* The scene after Hogarth [[spoiler:nearly gets vaporized by the Giant when they were playing a game and the Giant mistook Hogarth's toy gun for a real weapon, and Dean yells at him, calling him "a big gun that walks." Giant then gets a "[[MyGodWhatHaveIDone My God, What Did I Almost Do?]]" moment when he sees a bus with a vaporized hole as Dean tells him, "You almost did ''THAT'' to Hogarth!"]]
** "I- I not gun."
*** Later echoed for a SugarWiki/{{Awesome Moment|s}}.
* The scene where the Giant approaches the dead deer, and learns about the concept of death for the first time. [[spoiler:Even more sad considering [[HeroicSacrifice what happens to him]] later on.]]

* What happens when you combine the Tear Jerker endings of ''Iron Giant'' and ''Disney/WreckItRalph''? [[http://www.youtube.com/watch?v=4fvLRA2W1wM Cue the waterworks.]]
* [[http://xombiedirge.com/post/56952728193/you-are-who-you-choose-to-be-by-adam Superman.]]
* Ted Hughes, author of the original novel who [[ApprovalOfGod absolutely loved the film]], died mere months before it was completed.
