Of course there are going to be things missing. You're being completely unreasonable. They only have so much time to fit in scenes from the book, while establishing the characters so that we can care about them.
Almost every actor did a terrible job even Oldman who seems to be playing six different characters, none of them the Count.
Dracula was a creature of many faces and attitudes even in the book. And how can you not say none of them were accurate? Unless you want to be petty and say that old man Dracula didn't have breast hair-buns in the book. The personality was intact in that case: a visually creepy, yet polite and very accomodating host. There's malice lurking under the surface that very gradually surfaces, and we discover along with Jonathan that Dracula is a demonic freak of nature. He's able to defy gravity by easily scaling walls. He feeds a baby to his three hedonistic whore wives.
Explain to me how that's "not the Count." The ingredients are there, save for some aesthetic alterations. So many compotents are present in fact, that naming him "Dracula" was very accurate to what we're given in the book.
Lucy being a saucy strumpet before getting bitten (if she acted like that in real life she would have been Seward's patient not the object of his suit),
She barely had a personality otherwise. Are you slamming the film for adding to a character? I personally thought the phallic connotation of her grabbing Quincy's large knife was funny. The way Lucy was handled in the film, even though she did have her legs spread the whole time, helped us take Dracula's threat seriously when he attacked her both times in wolf form. Here, she's a believable female wanting to break out of the shell society is trying to impose on her.
Some of the material usually unseen from the novel is put back but lacking any purpose (like the gas plumes that the Count uses to find buried treasure to fund his activities being nothing more than window dressing).
Lacking any purpose? Being said by the guy who listed these as unforgivably missing from the film:
No Golden Krone, a blink and miss it first coach ride, the killing of the baby's mother missing, most of the Demeter voyage and arrival missing, most of the Whitby scenes missing, Lucy's mother missing, Lucy's silly innocence missing, Lucy's first encounter with with the vampire hunters missing, Mina's oral rape scene inverted so she is almost attacking him, and there was so much in the film that made no sense at all.
