Well it has been a while (over a year) but to go back to the argument, most of Jackson’s changes were part of the necessity to simplify the construction of the story, but some of it was due to his reimagining parts of the characterization, often to simplify. In my mind the worst of this is what he did to Denethor, turning him from a tormented individual damaged by trying to fight Sauron directly, through Palantirs, and defeated as anyone would be in that struggle. He turned him into a demented and gross cowardly fool! Reprehensible!
True. That was a little worse than Frodo GIVING the ring to the Nazgul. At any rate, simplification is all well and good, but if you provide proper visual imagery, it shouldn’t be necessary. There’s just no excuse for cutting out Tolkien’s beautiful language.
