Having listened to the score several times now, I'd call it a disappointment and not real interesting.
I'll own up to not being very musically sophisticated - I can't be too specifically analytical. The music on the album, though, seems to me to be pretty repetitious with not a lot of strong motifs, a kind of indistinct blur of horns and percussion simply repeating the brief signature of the movie's theme in one variation after another.
The movie theme itself is derivative of other modern film scores - yeah, "The Dark Knight," even if it's a little "brighter."
The way in which the Courage theme and fanfare are used seem unimaginative to me (with one brief exception at the end of "Nero Death Experience") and rather obligatory - "well, we have to put it somewhere, make it a little lush and stick it in here."
Overall I was hoping for something more evocative from the guy who scored "The Incredibles," which is one of my favorite movie scores of recent years.
