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.
Author Avatar: Not necessarily Ana. Mrs. Robinson's initials are E.L.
Awesome Music: The trailer makes good use of a new goth-style and positively eerie redux of Beyoncé's "Crazy in Love".
Canon Sue: Ana not only gets to date a super-hot man. She also gets promoted from secretary to editor one week after being hired, even though she spent more of her working hours emailing Christian than actually working.
Fetish Retardant: The tampon scene. Also, the way Christian speaks of Ana's virginity like an obstacle to be removed.
The internet went berserk when casting was first announced, and a petition demanding that the current duo be replaced by Matt Bomer and Alexis Bledel gained thousands and thousands of signatures.
Nor were fans pleased when it came out that the book's sex scenes would be "toned down" for the film.
Pacific Rim and Sons of Anarchy fans were not pleased when Charlie Hunman was cast as Christian Grey, citing that he's going end up like Robert Pattinson and creating a bunch of Pacific Rim/50 Shades jokes. But when Hunman backed out, his fandom rejoiced.
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.
