It's gladiator.
I mean it's not even close.
Like listing John Williams and forgetting Star Wars.
popularity, melody, memorability, execution, atmosphere, appropriateness and most important of all - melding with and uplifting of the underlying material.
it's rich, complex, impossible to forget and cements the atmosphere and scale of the film. Like Lord of the Rings and Howard Shore, it's fantastic on its own merits but married to the film they both become more than the sum of their parts.
it not original or unique and it borrows a ton of cliches - middle eastern mystery from Lisa Gerrard, antique sounding instruments, bombastic and melodramatic tunes and on the nose military marches but it all works perfectly.
