Half Backed sure is a terribly bad movie! When it was inflicted upon me during the bus drive of a trip from school I could almost feel brain cells die as it was running on the screen!
One thing that really disturbed me about the 3rd Lord of the Rings movie is how they presented Denethor, the steward of Gondor. In the movie he comes just across as a mean guy. In the book however I felt great pity for him, and it appears more like he was driven into insanity by Sauron. Really, they should have at least mentioned Denethors Palanthir, and it sure wasn't necessary to let him run all across Minas Tirith so he could fall down that cliff for spectacularities sake. They should have granted him the impressive ending he had in the books.
