It's so tricky trying to review The Silmarillion, because I've been reading it since I was a child. It is in large part responsible for my love of world-building and my tendency to look for more behind every story; but I can also see that it's a history rather than novel and often quite dry. It's also problematic. The Elves are elitist and racist, and almost all Men are awful and doomed to die (don't ask about women - they just die).
...and yet. And yet. It still moves me, and regularly brings tears to my eyes. I'm far too emotionally engaged to be remotely objective about it. It's a must-read for any Tolkien completist, although you miss very little by skipping everything but the Quenta Silmarillion itself.
