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: Fifty Shades of Grey
Author Avatar: Not necessarily Ana. Mrs. Robinson's initials are E.L.
Fetish Retardant: The tampon scene. Also, the way Christian speaks of Ana's virginity like an obstacle to be removed.
Narm: Plenty of it, particularly in sex scenes. For example: "You. Are. So. Sweet,” he murmurs, each word a staccato. For the rest, see this tumblr.
Nightmare Fuel: It's horrifying how many times Ana is struck, raped and/or abused without her consent...and yet this is presented as not only romantic but the a relationship to aspire to.
Padding: The Email conversations and the submissive rules and contract that are printed in the book twice take up a lot of space without adding much content.
Serial Numbers Filed Off: Even though supernatural elements are removed, character templates remain mostly same. Which is okay for fanfiction, but not really when it's done for profit. Opinions vary on whether Stephenie Meyer should have sued.
