Gollum is the best character. He is the Darth Vader of the trilogy: His tragic quest for ultimate power leads to a brush with redemption and eventually claims his life as he steals the entire story.
I'd have to say Andy Serkis as "Gollum/Smeagol".
His performance was sheer genius, to say the least.
I also enjoyed Sean Bean's time as Boromir.
