Good essay...but to put the fine point of criticism on it, Hollywood cannot take much (or any) credit for it. It was created essentially by New Zealanders in New Zealand.
If Hollywood had had a hand in it, then it would not be the movie it is today. It would have been corrupted, and Tolkien's vision completely distorted and misinterpreted. It would have been "politically-corrected", if you will. Thank God it was made *away* from that poisonous and sick environment.
