Indeed- that is, to agree with the piece immediately above me.
I am not a fan of Potter (was, but am no longer) and have had this discussion (in all its variants) with my college roomate, who is a valiant Potter supporter- probably some of the liveliest discussions we've ever had.
Does Rowling copy Tolkien? At the very least she borrows some elements- but then, so do all major fantasy writers these days, after all, "There is nothing new under the sun."
Yes, Tolkien did borrow from all manner of mythology and language- dwarven runes are Old English, his Elvish is based heavily on Latin, Norse mythology featured heavily, and the books are riddled with Christian theology- none of which is a bad thing, and ultimately, in my opinion, add to the fullness and richness of Tolkien's works.
Which is why I too am distressed when I find that more of my generation have read/ watched/ breathed HP than know that Tolkien exists (yes, actually- I have met people who have read HP without seeing LotR...). And I would not be surprised to find the world, at some point in the near future, heralding HP as the next generation of 'remarkable fictional literature' to have ever been written, and, give Rowling a hundred years or so, being taught as a classic. No, this doesn't please me, because while her stories are engaging, her writing style and the ultimate summation of her stories are far inferior to that of Tolkien.
Be that as it may, at least they are better than Twilight.
