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.
YMMV: The Official Fanfiction University of Middle-earth
Evil Is Cool: Deconstructed with the subject "Evil Is as Evil Does 101", taught by Sauron himself, to teach that Evil is more than calling yourself evil because it's cool and dark and edgy. Like causing a river of blood, at least.
Ho Yay: Deconstructed in "Platonic Love 101" by Frodo and Samwise, and "Male Bonding 202", by Legolas and Gloin. Shows what's really behind it. When a hug is just a hug and such.
