I agree that Tolkien didn't invent fantasy, because of course I have to. But Terry Brooks's breakthrough novel THE SWORD OF SHANNARA is a point-for-point riposs of THE LORD OF THE RINGS. There is a Gandalf character, a Frodo character, and an Aragorn. There is an undefined villain we never really get to meet and an artifact that needs to be found, or destroyed, or both, in the villain's lair, which is reached by walking. Along the way they have to hide from "Skull Bearers" and their encounters with these indestructible superfoes bear such strong similarities to the encounters with the ringwraiths that I shouldn't have to make the argument. Frodo flees the skullbearers that come to his hometown (!) and goes to the town of Leah where a council is held and it is decided that group of various races and classes should walk to the Warlock King's domain and steal a sword, which was the only thing that could kill him. The group loses track of the Gandalf character when a note left for them with some bartender in an inn is either lost or misread, and later the Frodo character gets separated from the group when he fall off a cliff or something, so he has to deal with the artifact alone.
Finding common comparisons between one fantasy story and another is a fun game to play I know, and if you are superficial enough you can find them anywhere. In this case however this is not the game I am playing. I am not looking for generic similarities and thereby concluding that all fantasy is ripped off from Tolkien. I am talking about this one specific book, and the similarities are pretty damn direct and they all occur in the same narative order. If I rememebr it right, at one point they even believe that the Gandalf character has been killed but later it turns out he wasn't. Meanwhile there's a kingdom under attack and its king is isane and needs to be ousted by one of the heroes so that the kingdom can defend itself from the armies of the unseen Warlock Lord that Frodo is off to face. THE SWORD OF SHANNARA is a summary of THE LORD OF THE RINGS. The plot is so directly similar that it's amazing he gained any readers and wasn't turned on immediately by fans of the genre.
Fantasy editor Lin Carter denounced The Sword of Shannara as "the single most cold-blooded, complete rip-off of another book that I have ever read". Elaborating on his disapproval of the book, Carter wrote that "Terry Brooks wasn't trying to imitate Tolkien's prose, just steal his story line and complete cast of characters, and [Brooks] did it with such clumsiness and so heavy-handedly, that he virtually rubbed your nose in it."
That last paragraph stolen from the section "Similarities between Sword and The Lord of the Rings" in a wikipedia article, which includes many other famous authors' negative takes on the novel, including Tom Shippey and Orson Scott Card.
http://en.wikipedia....ord_of_ShannaraOne thing I learned from that article is that a film is in the works of ELFSTONES OF SHANARRA; I supoose the filmmakers knew that a movie of SWORD would receive too much criticism. It says that they would hope to make a SWORD movie later, but I would really be surprised. It would be virtually impossible to distill that story into a film without making its derivation obvious even to the dumbest child.
