* BoomHeadshot: In "Broken Glass" Naomi shoots the killer she's been tracking (really a vampire, though she isn't aware of that) in the chest multiple times (as she's trained to) before finally shooting him in the head after the rest don't even slow him. This kills him, with her being spooked about it.

* OhCrap: [[spoiler:In "Intercessions" Mark sees a photo of Isaiah's father when he goes to pick up Eleanor at his house, realizing he's the man who he'd murdered. Not only that, but then Isaiah's mother tells him she's a homicide detective with the NYPD. You can see the succession of dismayed emotions that Mark just manages to cover.]]

* PintSizedPowerhouse: Eleanor, as a result of being a vampire, can take grown men down due to her having increased strength although she's stuck physically twelve forever.
* RaceLift: In the original story the characters are entirely white. Here Mark (based on Håkan) and Eleanor (who originally had been Eli) are Latino. Isaiah (based on Oskar) is black.

* WeakenedByTheLight: As usual, vampires here are harmed by sunlight. It's shown in the very first scene as a young male vampire starts to burn when the light hits him, and with Eleanor later as well. Peter, as the first male vampire's revealed to be, gets left with hideous burns.

* CreatorBacklash: John Ajvide Lindqvist revealed that Hammer tricked him into signing away the television rights and is not getting paid for the show. “The only thing I've seen is the trailer, where there is some from the book and otherwise it's general vampire nonsense.”

* InternalReveal: Isaiah slowly realizes that Eleanor isn't an ordinary, as a result of her glowing eyes and never eating. She confesses that her eyes glow from seeing in the dark, and she's incapable of eating anything but blood. Though the word "vampire" isn't used, clearly Isaiah knows what this means from the look on his face. All this is after the audience had seen from the beginning that she's a vampire.

* NotGrowingUpSucks: Eleanor is a vampire girl who's stuck permanently as twelve, physically anyway. She isn't happy at this, still having to blend in by attending school repeatedly.

* AdaptationalHeroism: Håkan in the novel is a pedophile with prurient motives in serving Eli. Mark, in contrast, is trying to keep his vampire daughter alive and find a cure.
