[Captain of Despair]

MY least favorite would have to be Denethor. I know it's been mentioned a thousand times, but I cannot get over how they ruined the character. Sure Denethor (in the book) had become somewhat maddened due to everything that had happened (Boromir dying, Faramir becoming ill, terrible visions in the palantir) but over all he was still a good man. In the movies he was portrayed as little more than a raving lunatic. But I digress.

Honorable mention in this category goes to Gimli. He was turned from a great warrior to a bumbling joke. Enough said.

Favorite character is extremely hard to pick, but if I have to choose I will make it a tie between Merry and Pippin. I'm not sure exactly why, but I just love those little guys. The actors and their portrayals were top notch.
