Those Twilight movies make bank too but I bet you no one here could name any of the characters from them.
A LOT of people can't.
They're just movies. And not everyone has seen them.
But I bet you everyone here knows who Dracula is. Cause Dracula is THE vampire. He's the archetype. His name reaches beyond media. He's engrained in our culture. Every kid knows who Dracula is by the time they're like 3 years old.
Superman is the archetypical superhero. The origin of the term "superhero" lies with Superman. He has his own logo. He has his own smiley on the coli.
Every single person alive knows who Superman is, where he came from, who his girlfriend is, what his weakness is, etc.
He is the most WELL KNOWN character ever conceived in american fiction.
