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.
Crazy Awesome: Special credit to Crazy Jane and Rhea post-transformation.
Nightmare Fuel: The matter-of-factness of the art style makes the 1960s version of what Negative Man looked like under the bandages truly disturbing. Grant Morrison's run quite deliberately injected quite a lot of horror imagery.
The Candlemaker. Sweet Jesus, the Candlemaker.
The entire arc with the Scissormen, especially when they first start to breach reality.
Some Anvils Need to Be Dropped: While some argue that Coagula from Rachel Pollack's run was a Mary Sue, the fact of the matter was that were virtually no other positive representations of transgender characters in comic books at the time, so it's no wonder that Pollack strove to create a strong and competent transsexual superheroine.
Values Dissonance: When it turned out Monsieur Mallah and the Brain were in love, the reaction of most people was "OMG, they're gay! That's disgusting!" Never mind the fact that one's an ape and the other a brain in a jar, it's the fact that they're the same gender that they found offensive.
