Unsurprisingly, The Spectacular Spider-Man, the best superhero cartoon of all time, broke the mold a little bit and gave us a Halloween episode that's a little more think-y. However, all this metaphorin' doesn't prevent the episode from having a fight between Green Goblin and Spider-Man which takes up the entire third act. That was probably the greatest strength of the show: being able to balance teen drama and deep reflection with radioactive boxing matches that usually lasted about seven glorious minutes.
While most interpretations of the Green Goblin never get past the whole "Curse you, Spider-Maaaaaan" section of their shtick, this Green Goblin is a playful, sadistic dick. He's constantly asking Spider-Man to consider what "mask" is real -- the mask that hides your face or the mask that is your face. This doesn't just play into the mystery of who the Green Goblin is, but also deals with something that's lacking in a lot of superhero shows that are made for kids: At what point does your human identity become the facade? The Green Goblin and Peter Parker aren't opposites; they're both freaks who only find respite and fulfillment when they wear their masks. Peter Parker is a bespectacled shell of a nerd. It's only when he's Spider-Man, quipping and punching with psychopathic consistency, that his actual mask gets taken off.
Anyway, Green Goblin (Norman Osborn) fakes a leg injury and then retreats back to his home. There, he finds his son passed out, breaks his own son's fucking leg, and puts the Goblin costume on him. Then, when Spider-Man gets there, Norman is all like "We gotta get my son some help. He's really sick. See, his leg is broken. He's helpless. WINK." So yeah, if you want to watch something with all the fun of a Marvel character and all the "Oh my god, no" of comic book child abuse, this is a good one. Jeez. Maybe you should've just gone to a costume party or something, y'all.
