Here it is. This is the definitive “Lord of the Rings” as cinema has decided to depict it. No, it still isn’t faithful to the books but we’ve established this. Taken on its own or with respect to the first two parts, “The Lord of the Rings: The Return of the King” is probably the most consistently entertaining picture that spans a length of 200 or so minutes that you are ever likely to see. You know how I said “The Two Towers” was better than “Fellowship of the Ring“? Well this one dwarfs both of them.
