My main issue with The Lord of the Rings will always be its utter lack of female characters. Tolkien was writing at a time when women fighting for their rights was a central theme in most western societies, and yet, he infused his work with his conservative, regressive views on women.
It's such a letdown next to his obvious hatred of fascists, industrialism, and bad men.
@thomholwerda I thought Peter Jackson made a (rare) good choice in having Arwen save the hobbits from the ringwraiths instead of an elf who, irrespective of his importance in the Tolkein canon, has little else to do in the film. It tied her into the story and turned her into something more than a princess bride.
