Watched The Battle of the Five Armies. How many ways would the author be appalled?
Puppy-love between a canonical Dwarf and a non-canonical Elf. Their pheromones cannot be compatible.
There’s a Laketowner named Percy, a family name from France. (The other Laketowners at least have Nordic names, consistent with the author’s usage for Men and Dwarves of that region.)
The Orcs sneak up on Erebor using tunnels bored by non-canonical sandworms “were-worms”. Etymology time, since etymology was very much Tolkien’s thing: the first element of werewolf does not mean anything like ‘magical’ or ‘demonic’; it means ‘man’ (cognate to virile). Do these monstrous worms turn into men at other phases of the moon?
I rather hoped Thorin would live long enough to thank Legolas for the loan of a sword. “Almost as good as a Dwarvish blade.”
My mistake. In “An Unexpected Party”, Bilbo says
Of course there’s no canonical evidence that these legendary Were-worms are real.
