Fan of the book or not, I have heard J.R.R. Tolkiens work described many ways, but never campy.
People lets not forget a master whos genius cannot be overstated is the source of this material. Calling anything he put down, campy, is like looking at the Mona Lisa and saying Di Vinci was old fashioned cause he didn't use a digital camera.
This isn't twilight. This isn't Harry Potter. This is the work of J.R.R. Tolkien, arguable one of the greatest, and most influential fictional writers to have ever lived.
You don't criticize the classics for being old, you revere them for what they are. This book deserves more respect then to be picked apart by people who can't appreciate a masterpiece when they see it.
I promise you, with the same conviction you claim to know how Peter Jacksons brain works, that he doesn't look at things like Bert, Bill, and Tom, and say "ho hum, you know thats just a little bit silly for my taste, what were you thinking Tolkien, lets change that."
Again I sight the trilogy, if that was the case they would have renamed the whole cast. I mean Bilbo? Frodo? GANDALF? What kind of names are those? What about that ridiculous part about the elves, don't people know they aren't real?
If you start picking at threads, you might not stop, its best to revere the classics for what they are, and celebrate them. If you change them, you dishonor them.
*Please understand I am talking about changes for the sake of pleasing the masses. Obviously there are time constraints (Two movies at best 6 hours) And technological limitations, after all dragons and goblins and magic rings don't exist in real life either .
I will leave you with a quote that seems fitting: 'Needless were none of the deeds of Gandalf in life.' ~Galadriel
The same can be said about Tolkien, he is enough of a master of the art to give him the benefit of the doubt and say if he wrote it, he did it for a reason.
Campy.... Come on.
