LotR is about how the wisest and the strongest barely manage to survive while the weak save the world.

In the books, Gandalf states that expliitly: “Many are the strange chances of the world,' said Mithrandir, 'and help oft shall come from the hands of the weak when the Wise falter.”

In the movies, they even have the King of Gondor kneeling before the hobbits, just to drive the point home. It's hardly subtle.
