It’s just possible there’s someone reading this blog who, in 75 years, has never read The Hobbit. I know they exist, because that group of people includes my dad, though he has an excuse: he was 10 when it was published, and already not-interested in fantasy.
So, if you are among those people, this blogpost will spoiler you like anything for The Hobbit, or There and Back Again. (The fiftieth anniversary edition, with the lovely illustrations by Michael Hague, is at my elbow as I type.) This may also spoiler you for the movie, The Hobbit: An Unexpected Journey, in which Peter Jackson takes full advantage of the fact that he did a pretty good take on Lord of the Rings and any number of fans trusted him to do a pretty good take on The Hobbit, even though he is blatantly milking it for everything it’s worth and no one should let him even think about the Silmarillion, okay?
