I love the Silmarillion far more than the original series tbh. I reread it every few years, just a tremendous piece of work. Tolkien created a masterwork that really fleshes out Middle Earth (and the other continents) as a world with a history and myth that I can sink my teeth into. I love that it does do that to the elves, showing them to be just as vain and greedy as men. I'm a big epic poetry kind of guy and the Silmarillion scratches an itch closer to stories like Beowulf and The Iliad than LotR does.
