I don't mind Tom Bombadil being cut out of the movies... what I care most about is changing the personality of the characters they kept in. Tolkien has a very clear message to give in the books that I don't like to see muddied.
Oh my gosh. Nothing is being muddied, nothing is being ruined. If Jackson were to go to into the books and change up Tolkien's writing,
that would be muddying up the story, but making a
completely separate work and changing the characters
does nothing to affect the true, original work. Jackson can do whatever he wants with the Lord of the Rings. He can make it into a fairy tale and change Sauron into the Big Bad Wolf,
it doesn't matter. The books in their original form will remain completely unharmed. Books and movies are two completely different mediums of story.
