Frodo, the main protagonist of LotR, is a short, portly, middle-aged man possessing no magical abilities of his own, nor martial skill. He journeys to an evil land to destroy the Ring and with it the Dark Lord. The only battle he fights with the Dark Lord is one of willpower as the story progresses. There is no destined epic showdown between the two.
I don't say this necessarily in defense of Tolkien, as if the accusations leveled against other authors were somehow a slander to his writing. I say it mostly because it's frustrating to me that people can consistently get this wrong, as if they haven't actually taken the time to think about anything and just enjoy throwing words and phrases around to make themselves appear intelligent. It does a disservice to the fantasy genre as a whole, implying that the genre has been largely stagnant since Tolkien, that we can't seem to move on. In reality, the fact that this dashing, improbably powerful Chosen One cliche is even cliche proves that fantasy has not clung quite so tightly to Tolkien as is popularly spouted.
End of rant.
(If you're curious as to what set this off: I was reading reviews on another author's work who I'm interested in checking out, and several of the users were having quite the mutually-congratulatory discussion on how derivative the author's work was of Tolkien, in particular the Chosen One plot.)
