"I agree entirely with the reviewer, except about the allegory, which Tolkien said it wasn't.
Jackson reduced a fantastic story to a series of battle scenes between comic book baddies and tackily clad goodies (the Gondor knights' armours and Isildur's sord were particularly disappointing), preceded by rousing speeches or other displays of manly bravery and camaraderie. It was all so ineffectual and melodramatic. Especially jarring were all the endless teary-eyed scenes with Frodo.
In short, I'm really sorry for all you people who missed the visceral experience of reading the book without knowing where the story was going."
