For me, it would have to be the Lord of the Rings movies. Being an avid Tolkien fan, I was extremely concerned about the quality of the movies. Fortunately, Peter Jackson did not disappoint. I found many parts of the dialogue that were pulled word for word from the books. The scenery was also very well done. About the only qualm I have with the whole thing is the Gandalf / Saruman fight scene - I thought I had popped into a scene from the Matrix.
