Scream Queen is usually a girl ( they tried to create a male version of this with
Nightmare On Elm Street 2 but it was stereotypical and ridiculous).
She's sexy, often blonde with revealing clothes that gets chased on in horror movies and often die when she could've survive if she wasn't so dense when confronted to dangerous situations.
The Scream Queen could have been perfect in a **** film but I guess she thought the stigma of horror was not as heavy as ****... Needless to say she was wrong !
What makes a good Scream Queen ?
Well, she has to be cute, to be able to express fear convincingly, to scream really loud to run very fast and to be lovable too so when she dies while you're thinking "God, this girl is so stupid" you also think "I'm gonna miss her"...
I also noticed that she's often the ****ty/shady friend of the main female character (which is also a kind of Scream Queen) who seems to be methaphorically punished for her lack of morals.
My personal favourite :
Sarah Michelle Gellar
