Subjective tropes for the film:
- Anvilicious: The awfulness in the systematic discrimination and rounding up of the hemophages is hammered on in one particular scene where a family of hemophages is seen dressed up as Hasidic Jews, complete with biohazard patches.
- Big Lipped Alligator Moment: The Blood Chinois. They are a random Asian gang that randomly appear in the movie, have no apparent motive and backstory besides "You're in our territory", set up a ridiculous action scene, and they are mentioned precisely once later when Nerva's goons try to intimidate Violet by reminding her they aren't Blood Chinois, as if we knew enough about them to use them as a gauge of strength.
- Dueling Movies: With Underworld Evolution or Blade: Trinity or possibly both and maybe even with 30 Days of Night, which would explain why the vampire subtext seemed a little buried.
- Faux Symbolism: The prologue shows hemophage victims wearing black hats and clothing, being harassed by skinheads, and herded into camps. This sequence serves no narrative purpose and is never referenced again.
- Possibly because after the opening sequence, almost all the hemophages were executed? As Violet herself says, "The ones that survivedů started fighting back."
- Fight Scene Failure: Whilst Storming the Castle, Violet faces one room full of Mooks in pure-white NBC gear, which just makes the Bloodless Carnage all the more blatant. Combined with relatively tame choreography, this fight is a particular low point in the film.
- The duel between Violet and Daxus has its problems, too. The idea is So Cool, It's Awesome—a Sword Fight in total darkness, lit only by the fact that the swords are on fire—but because they actually filmed it straight, without employing Hollywood Darkness, you can't make much sense of what's going on.
- The final fight with The Blood Chinois is one, too. It's more or less the same shot over and over.
- Just Here for Godzilla: Milla herself is the reason many caught the movie.
- Moral Event Horizon: The Ministry deliberately terminated Violet's pregnancy. She doesn't know this. Neither does the audience.
- It's a blink-and-you-won't-hear-it moment on the soundtrack—when she escapes with the "package", a voice identifies her as "a plague victim whose pregnancy was forcibly terminatedů"
- So Bad, It's Good: A Guilty Pleasure for many.
- Special Effects Failure: the CGI was decent for its time, but it doesn't particularly hold up today.
Subjective tropes for the television series:
- Body Horror: In Episode 2, a girl who had her back completely and utterly broken in a motorcycle accident is turned into a vampire. There is a blood-chilling shot from behind in which you see her back is still broken, even as a vampire.
- Fanon: There's a belief among some fans (and on the packaging of some DVDs) that the central characters' unnamed organisation is called the CIB. This is a misunderstanding of dialogue in the first episode, in which their cover story to the police is that they're working for the Complaints Investigation Bureau, which at the time in real life was the name of the Metropolitan Police's Internal Affairs unit.
- Hot Scientist: Angie March.
- Squick: A vampire accidentally runs down a young woman and breaks her spine in multiple places, paralyzing her for life. He then turns her into a vampire so she can walk again. She's still wearing her hospital gown when she confronts Michael, and her back is exposed. The pieces of her spine are visibly misaligned under her skin, and every time she moves there are clicking sounds as the bones grind together.
