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: Blood and Chocolate
Darkness-Induced Audience Apathy: Everyone in the story is an asshole, and the entire plot is set up in such a way that you can see well before the end how this will end badly. At least Twilight ended well for its protagonists!
Fridge Logic: Werewolves and humans can't interbreed. Werewolves tend to kill each other over mates. Why are there still werewolves?
Mary Sue: Is it possible to be too good-looking? our heroine wonders within the first few pages of the book.
Special Effects Failure: Just one of the feature film's problems, the werewolf transformations have the characters leap in the air, start to glow like Christmas trees before dropping down on the ground as normal wolves.
