Having seen the films is not geeky... having read the books a hundred times along with ever piece of lore ever written, knowing every character and creature off by heart, being able to speak the language - that's geeky. Anything can be considered geeky if you're interested enough in it, but the elves and dwarves and fairies and mythical creatures make it more geeky than your average franchise really. Anything fantasy or sci-fi related is closely associated with geek culture.
