Sticking to the story line?
One ofthe best trilogies ever made, but would have have been even better if Peter Jackson had stuck solely to the story line.
For instance where in Tolkien's book does the elf Arwen ( Liv Tyler)carry Frodo over the river away from the black riders?
I think it's a bit arrogant of directors to think they should change parts of a literary Masterpiece to their liking.
The 1970 cartoon version is more faithful to the book.
