That's insane because i think it's clearly one of the most iconic superhero scores...
Up there with Elfman's Batman, Williams' Superman, and Zimmer's Batman.
I think most would agree.
I honestly think Elfman's Spider-Man score is so musically complex that it gets overlooked sometimes. DaDuhDaDaahduh-Elfman Batman
Da-Da-Da-Da-Da-,duh-duh-duh-,Da-da-da-da-DADADA!-Superman-JW
But Elfman's Spider-Man theme is like a mosiac of themes mashed together.
If you didn't give yourself time to listen to it, I think it can easily blend into the background.
Horner's theme (RIP) had that nobility that captures the warmth of Spider-Man, Guichinno had a sort of musical wittiness (the theme is basically half the phrase of the 1960s Spider-Man theme), Zimmer proved that he could make forgettable music (so there's that :P) -but none of the film composers have captured the sheer energy and intensity of Elfman's Spider-Man music.
The drums are intense loops that make one think of feet running, the arpeggios make one think of dizzying speed and heights, the complex chord structure providing both a sense of wonder and disorientation.
The chorals honestly add an otherworldly quality to the music, giving it a kind of etherial eerieness which adds to the overall atmosphere.
The theme seems to alternate between sounding creepy and triumphant, almost as if it's exploring the character's duality musically.
I could go on and on, but if you don't think this is at least a DECENT superhero theme, I don't know what to tell you.
