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.
Anti-Climax Boss: The final confrontation with Dracula takes less than three pages, and that includes the heroes fighting off his mooks.
Evil Is Sexy: Averted with the Count himself, who is an ugly old man who physically repulses Mina when she first sees him, unaware of his identity, but played straight with Lucy - her vampire self is considerably more sultry and seductive than her original, innocent persona.
Likewise with the brides.
Foe Yay: Dracula and... well... everyone. Especially Jonathan. "He belongs to me!" indeed.
Praising Shows You Don't Watch: Some people call Sadly Mythtaken on many things saying that "Dracula never sparkled" or "Dracula never went out into the sunlight". The former is more or less common sense, but the latter pretty much shows how much they read Dracula. This is probably due to Lost in Imitation, all adaptations are based on either Nosferatu (where sunlight is made the way to kill him) or the very simplified play.
Ron The Deatheater: Van Helsing tends to be portrayed as this in re-tellings from Dracula's point of view, where he's seen as radical and clueless; he particularly gets flak for the transfusions that, admittedly, could have killed Lucy in real life - leading to said re-tellings claiming that Dracula turned Lucy in order to 'save' her life - but at the time the book was written, neither he nor the author would have known that.
Squick: Lucy's gums turn pale from Dracula's blood-sucking. Erk!
Values Dissonance: The casual antisemitism displayed by Harker, the sexism, the xenophobia, and such would have been seen as perfectly normal and cultured for the well-to-do British reading this novel when it first was published.
In the novel, Dracula is Mina Harker's metaphorical rapist. In all movie adaptations, he's Promoted to Love Interest. Make of that what you will.
The story is rife with the casual sexism of the time: for instance, when Mina has a bright idea, Van Helsing remarks that she has "the brain of a man". However, an open-minded reading will show a deconstruction with a strong feminist leaning, as the men are perpetually useless at anything except a straight fight, while Mina is the only character to be consistently intelligent and useful throughout.
Sadly, this elemant takes a critical hit in most movie adaptions. most notably, in the Bela Lugosi version, she's portrayed as nothing more than a wimpering child in an adult body.
What an Idiot: No one seems to find suspicion in the fact that Mina is displaying the same symptoms as Lucy when she was being fed on by Dracula, including her own stinkin' husband!!
The Woobie: Arthur. He loses his dad, his fiancee, and his soon-to-be mother in law in less than a week of each other. And then he has to kill his undead fiancee, who's turned into an unholy abomination against nature.
And then his best friend dies.
Jonathan as well, to some extent.
Mina, to the fullest extent.
taken Up to Eleven in the BBC version (the most faithful adaptation of the novel yet made, despite the following change) where she's Lucy's sister.
Narm: It's atmospheric, the villain is great... but man, most of it hasn't aged well and it's unintentionally hilarious.
For decades, the sounds of Renfield screaming while being strangled and Dracula's dying moans were censored out, so for most of the film's existence, we just get a short "Huullchk!" when Dracula is staked.
Special Effect Failure: It's blatantly obvious that the bats seen in the film are just rubber puppets on fishing lines. This contrasts with some of the film's other effects, like the glass matte shots which are quite convincing.
Signature Scene: It's either Dracula welcoming Renfield to his castle, or the brides walking through the catacombs.
Uncanny Valley: An odd auditory version. Bela Lugosi spoke very poor English, and learned his lines phonetically. This naturally resulted in Dracula sounding perhaps like he isn't quite used to speaking at all.
This is actually something that's been debated. For many of Lugosi's early American stage roles he did learn this way, but by the time Dracula was made he was probably a good enough English speaker to speak fluently. Compare Lugosi's speaking to Dracula, which he had played on stage previously, to Murders in the Rue Morgue a couple of years later and you can hear a more natural-sounding if still accented English.
The 2013 television series:
Critical Research Failure: Historical accuracy obviously isn't what this series is interested in, but oil wasn't discovered in the Middle East until 1908, twelve years after the events of the series. Grayson acts as though its existence in the Ottoman territories is common knowledge.
Grey and Gray Morality: Neither side has clean hands. Even Van Helsing is morally questionable, having been responsible for bringing Dracula back to life in the first place by killing his tomb-raiding partner and letting his blood drip down on the dead vampire's dessicated face.
Les Yay: Interviews with a cast have already more-or-less confirmed that Lucy has a crush on Mina.
