Well, while I always liked "The Lord of the Rings" as a book, I never got myself to really like "The Hobbit" as a book - maybe because I never read it as a child, who knows?
I understand those, who have sentimental feelings about the book and feel that the movies are overdone. But as a general Tolkien fan and a fan of the way Peter Jackson put his world onto screen, I frankly cannot get enough of it - even if parts are only loosely based on the book or added by the film team completely.
The Hobbit has ecome more "ring'ish" in the movies, if you know what I mean. Nobody expected a children's movie to be made from the book. And the movies are meant for a broader audience, not only for book fans. All the Tolkien movies are a vision of a certain group of people and thankfully that vision seems to be in compliance with the vast majority of the book fans and those who never read the books.
Those who find it hard to accept, that their beloved book stories are being visualized in that way, have my sympathy but frankly it's time they should stop complaining - we all got the message. I have gotten that message again and again over the last 10+ years and frankly I cannot hear it anymore. It has become annoying, sorry...
If someone cannot bare the movies, just don't watch them. Keep to the books, if you want to. But for me as a guy who equally enjoys books and movies, the way Tolkien's world was translated from print to the screen, is simply an amazing achievement and I wish all book adaptations would have that quality.
