Meh... If JRRT himself was still among us you wouldn't even recognize LoTR by now, he loved rewriting his stories, merging characters, adjusting them or even wholesale turning them from good to evil or viceversa.
So in the movies we had lots of changes, I found some were great, some understandable, a few questionable, and one or two downright wrong.
So, ok, no Scourging or Bombadil or Glorfindel... but hey, all the rest was there, gorgeously rendered and the story got across.
What do you want him to do? a 6 hours movie that gives someone a tourist-class-syndrome-coronary and gets him sued?
