Alright, I'll be straight with you. I read the Hobbit, the Lord of the Rings, and the Silmarillion in the pre-Peter Jackson years, back when you were made fun of for liking fantasy anything. These days, I'm not into movies or games or whatnot that contain magical faerie creatures, but I still appreciate the storytelling and the insane amount of detail that J. R. R. Tolkien put into his work.
Now, with all that said, I found this cool documentary on YouTube. It's a History Channel documentary, which means it is a finely honed mix of re-enactment, scholarly opinion, and overly dramatic narration, but it's cool anyway. If you have 45 minutes to spare, check it out.
