At the top of my head, two really stand out, as I rewatched them both recently, I could appreciate the contributions made even more.
WALL-E
THE DARK KNIGHT
Especially in THE DARK KNIGHT. Without this engaging score, a lot of scenes would drag on.
"The Spectacle has, indeed, an emotional attraction of its own, but, of all the parts, it is the least artistic, and connected least with the art of poetry. For the power of Tragedy, we may be sure, is felt even apart from representation and actors. Besides, the production of spectacular effects depends more on the art of the stage machinist than on that of the poet."
--Aristotle
