I like how Bob doesn't understand that LOTR was developed independently from American sword and sorcery fantasy. While they both share some pseudo-historical trappings, they developed independently in parallel at roughly the same time.
American pulp fantasy a la Howard and Leiber was published in the pulp magazines by enthusiastic amateurs that were trying to eke out a living writing. Tolkien's fantasy was developed as both a place to play with his invented languages and provide a "lost" mythos for Great Britain, but he wasn't primarily a novelist, he was a professor by trade.
There was no subversion. The first really trope subverting fantasy didn't come along until Michael Moorcock decided to put a sickly albino wizard front and center instead of a wandering mercenary like Conan.
Star Wars doesn't subvert anything. It's just a melange of ideas George Lucas ripped off from Flash Gordon, Kurosawa, Wizard of Oz, The Dam Busters, King Arthur, Triumph of the Will, Asimov's Foundation, Herbert's Dune, and Kevin Bacon.
