James Horner hasn't written anything original since Legends of the Fall. Sure, the score works and doesn't distract you... that is you have never heard Willow, Apocalypto, The Four Feathers, The New World, Glory and so many other scores. And, please, someone do something about that damn "four note danger motif"!
And James Cameron is a douche. He hyped this half baked movie so we all thought it was his magnum opus.
If CC humorously criticizes Tyler Bates for plagiarizing Elliot Goldenthal, what makes Cameron's tired and worn out pastiche of Pocahontas and Dances with Wolves any different?
I never I thought I'd say this, but WHERE'S TITANIC WHEN YOU NEED IT!
