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.
Designated Protagonist Syndrome: Dani (normal schoolgirl who finds herself dragged into a very abnormal situation) is an interesting enough character, but when compared to David (alien vampire who murdered his father and is now on the run), Terror (alien with a verynote read: not been explained yet ambiguous agenda), Abihira (alien, assassin, David's sister) and Vlad (he's Dracula. Enough said).
Nightmare's army is made from the remains of aborted babies.
Villain Protagonist: It might be a stretch to say David is the main protagonist (that's Dani), but he's supposed to be better than Terror. We don't know what she did, but we know what he's done, and he's hardly a hero.
What an Idiot: Dani. She should know there's something strange about David, but she won't stay away! And why did she tell Edward about InGEN?
