Now a whole new generation of Tolkien fans will come to the fore, via the movies. The fact that Peter Jackson is even attempting to film the LOTR Trilogy raises the hackles of a huge population. You may call these people purists . They are worried the films will not be true to the source. Indeed, they despise any adaptation of Tolkien's work, for the stage, radio, or any visual media.
Nothing can hold a candle to the original.
Ultimately these people will fail to manifest the profundity of his work. There are Shakespeare purists too, who function much the same way. Personally, I greatly respect and anticipate Jackson's films, but I don't envy him one bit. He has the toughest of all possible audiences to please. It will be a near impossible feat.
