Tear Jerker / A Goofy Movie
After Max walks out on the Suck E. Cheese's, Goofy says he just wants them to spend time together as father and son. Max more or less says he wants nothing to do with his dad, ever again. You can just feel poor Goofy's heart breaking...
Max: This is the stupidest vacation! You drive me from home, and jam me in this dumb car to drive me a million miles away TO SEE SOME STUPID RAT SHOW! (inhales) Call me when the trip's over.
Much of the rest of the film contains them as well, but of the more positive variety.
Goofy's line to Max near the end hits a little too close to home.
Max: I'm NOT your little boy anymore, Dad! I've grown up! I've got my own life now!
Goofy: I know that! I just wanted to be part of it!
Goofy: You're my son, Max. No matter how big you get... you'll always be my son.
Max pounds the roof of the car on the word "not," eloquently conveying his frustration, and adding to the quality of the scene.
The hug between Max and Goofy after Max saved his father from falling in the waterfall.
Goofy's COMPLETELY destroyed expression when he discovers that Max changed the road map.
And, for that matter, the entire scene surrounding it too. When the map-change is first revealed by Pete, Goofy actually calls Pete on his accusation, marking the first (and only) time in the movie that Goofy actually stands up to Pete's belligerence. Yet despite Goofy insisting he didn't need to follow Pete's advice and check the map to see if it had been altered (because "I trust my son", showing just how much Max and Goofy's relationship had improved), the next scene shows Goofy getting into his car, clearly wrestling with himself on what he should be doing. He suddenly grows angry with himself for not following through on his own words and is about to go back inside, when he pounds his fist on the steering wheel causing the glovebox to pop open, discovering the truth... that Pete was actually telling the truth this time. Then, just because poor Goofy hadn't been kicked enough at that point, he gives Max one last chance to come clean in a Secret Test of Character when he demands to know which turn they need to take to get to Lake Destiny; despite a crisis of conscience, Max sticks to his original plan.
Goofy's bitter response to Max's attempt to explain. Hearing Goofy being genuinely hurt and angry is just devastating:
Goofy: Why bother? I'm probably too stupid to understand anything, right?
The scene where Max and Goofy are trapped in the car overnight. When Max expresses amazement over a trick Goofy uses to open a can of soup, Goofy explains that his father taught him that, prompting this regret-filled exchange:
Max: You two did a lot together, huh?
The sequel has the scene where Max leaves and Goofy is feeling lonely. Bumped up even more when you see the dead-end production line job he has. And then you realise that this single father has been doing this lousy job for three years (the previous movie had him as a child photographer) and still coming home cheerful and loving towards his son, and it's bumped Up to Eleven. The worst part is when he walks around Max's now-empty room before sitting on the bed and hugging his son's old teddy bear, sobbing. Many parents will testify that yeah, it's exactly like that when your baby leaves the nest.
Max's huge "The Reason You Suck" Speech to Goofy after the first X-Games challenge? It's pretty heart wrenching seeing Max tell off Goofy over something he doesn't know about, it add a huge punch where Max tells Goofy to "GET YOUR OWN LIFE!!" Which only causes Goofy to become depressed, fail an exam, and miss his date with Sylvia, who then is seriously angry at him for ditching her.
Max's guilty expression when he realizes his father was right about Bradley trying to eliminate his teammates in order to win. Especially when he calls out to Goofy through the Jumbotron:
Max: I need you.
Worse is his reaction when he thinks Goofy isn't coming:
Max: Guess he isn't coming... can't blame him.
A mild one for PJ, but at the beginning of the sequel when Max is complaining about Goofy, he quips to Max that at least Goofy isn't "counting the days before he can turn his son's room into a bowling alley", which is later followed by Pete ignoring Goofy's noticeable sorrow and mockingly shouting "C'mon son, I can't miss you if you don't leave!" and laughing. Ouch.
When Bradley shot Tank and Max into the X, it caught on fire. On Live TV. Goofy tried to save his son before it could happen too, so he had tried to do something; he ran RIGHT For the fire to save his son. Silvia was in the audience, so she's seeing her boyfriend trying to go into the inferno to save his son. THAT is heartbreaking for both of them and for anyone watching this in their world.
