These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
"Weird Al" Effect: An interesting variation — while LOTR itself is still familiar to the point that nobody past Middle School age can call themselves a geek unless they've read it, many of the sources drawn on for the Parody Names and such are all but forgotten. A working knowledge of 1950s and 1960s politics, pop culture and advertising adds a lot to the experience.
