How much Frodo grew...

[Rimbaud]

..and the Bebe-licious One as well, of course.

I think the filmmakers did not achieve as intended with regard to character development; this is despite, ironically, upsetting Faramir purists, purely for the sake of 'character development'. This idea of 'growth' through a film has become an obsession for many filmmakers and studios, often to the detriment of movies where it isn't an apt element...but I digress. In this case, as I think has been tacitly accepted above, the true measure of personal growth, in the book, is through the hobbit Frodo.

A case can be made for that of Aragorn, yet it is nto half so finely a drawn development through the text.

Yet although a comparison between the film-Frodo of the opening to FOTR and the closing (one of the many endings ) to ROTK will show what would appear a distinct change in the character, that development is not linear through the film in the same way it is in the book.

In the film, from Weathertop, Frodo is essentially a constant sad-eyed victim; this is patently not the case through the remainder of the novel. This is a great pity, for there are many fine things about the films but this was a central tenet that they were obliged to 'get 'right', and rather reluctantly, I posit that the team did not.
