Everything, book, comic books, film and song...everything with Elves and dragons, is LoTR. Everything. Tolkien didn't invent Elves in literature, no. But like Leif Ericson discovered the New World a couple of hundred years before Columbus, it was unimportant, and nothing came from it. Not until Columbus. Tolkien is the Columbus of all fantasy fiction. It's why there is an entire section dedicated to fantasy in every book store.
That didn't occur in literature or film until Tolkien. He didn't make it up, but he was most important. By far.
(Yes I know "A Midsummer's Night Dream" was all about Faerie, and Shakespear is the most profound influence on English literature...but there were no books about elves, dragons or orcs) before Tolkien)
