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.
Awesome Music: This movie had a pretty damn funky soundtrack that mixed creepy horror motifs with R&B and funk.
Complete Monster: Although briefly seen, the first film's incarnation of Dracula manages to be even worse than most other depictions. Not only is he a blood sucking monster, he's also involved in the slave trade. When the African prince and his wife come seeking his help, he turns the prince into a vampire, renames him "Blacula," imprisons him in a coffin to starve for all eternity (and because he was now an immortal vampire, his suffering would never stop), and starves his wife to death. Unlike Blacula himself, who is a tragic character and spends most of the second film searching for a cure for his vampirism, Dracula relishes in being a vampire, showing no remorse for anything he does.
Nightmare Fuel: One of Blacula's female victims reanimates in the local morgue, and the viewer gets treated to a POV shot of a luckless morgue attendant, as said victim comes charging down a hallway towards him in slow-motion, all fangs and crazed staring eyes.
Values Dissonance - Many of the comments regarding the two Camp Gay characters in the beginning are definitely a product of the 70's. The fact that the cops dismiss their deaths because they are gay is downright offensive to modern viewers.
Values Resonance: This is just another part of the movies stance on prejudice being wrong, though.
