Okay, that's true, the original Stoker's Dracula was intended to embody foreign fear, corruption, and old-world decay, not charm.
But in some movies and video games they're tring to add more selling points so they 'changed' him.
Vlad III the 15th-century Romanian ruler (the name Dracula was inspired by), also known as Vlad the Impaler or Vlad Draculea (meaning "Son of the Dragon"), was more scary and menacing than handsome.
It was his brother, Radu the Handsome (Radu cel Frumos), who's known notoriously handsome, providing a stark contrast to Vlad’s fierce and intense look.

Movie adaptions tend to make some leaps from the books.
For example, I
read heard the audiobook of Bram Stoker's Dracula and I thought, from all the movie adaptions I watched, none of them captivate the real charm and suspence of the original book! Especially scenes that never seem to made it to the movies. Like Jonathans carriage ride with the flames.
It made me question why no one has made a full-cast audiobook of it! The way it's told through letters, journal entries and newsclippings than just a standard book narrative makes it perfect for that!
But, as I tried to listen to Mary Shelly's Frankenstein... I quit half way through the book. Each chapter was mostly heavy context about characters or locations before taking a few short steps to the next part of the story. The movies really trimmed down the fat of the book and get straight to what we want to see.
Ironically, for a book so heavy in explanation, it mostly glosses over how Victor brought the monster to life. The whole lightning storm and "IT'S ALIVE!" thing was Universal Picture's idea.
