... I'm not sure what is hard about LOTR. I've read the series ~15 times. Try reading Virgil or Dante, those are hard books. LOTR!?! I read that for the first time in 4th grade, and made it through just fine. The Silmarillion, that was tough, basically the bible for middle earth.
I also was very disappointed to not see Bombadil in the movies, not to mention old man willow and the barrow wight. LOTR is so amazing, as has been already said, because of the breadth of it. The history, linguistics, and geography of Middle Earth is far more developed than other "worlds" such as Star Wars. Keep in mind Tolkien not only created the characters and their interactions, he created a whole world! Hell, the Balrog has as much history to it as any Star Wars character. And through all of this "big picture" world-making, he still takes the time to describe the little Elanor flower in the golden wood, and to tell you (in elvish) what exactly the ring says. "Ash nazg durbatulûk, ash nazg gimbatul, ash nazg thrakatulûk, agh burzum-ishi krimpatul." One ring to rule them all, one ring to find them, one ring to bring them all, and in the darkness bind them.
I think this makes me a Tolkien dork, but that's okay, I saw Return of the King TWICE on opening day. Watched it in the theater, walked out and bought another ticket and went right back in. I had been waiting for those movies since 4th grade after all. Oh yeah, if reading the series that many times didn't make me a Tolkien dork, my "One ring" wedding ring kind of gives it away.
Oh and as for "Brokeback Hobbit", I got somewhat of this from the books. Towards the end of Sam and Frodo's journey, Sam does get a little bit gay there.
