Nosferatu
I think Nosferatu is a big picture of Ellen trapped in her own body and society.
Nosferatu, depicted as a monster who terrorize Ellen and her husband on the movie because of the non-consent relationship of him and Ellen when she's just a child.
I think Nosferatu is a whole bigger picture rather than just Ellen's abuser. He's a mirror to Ellen's desire whom the society condemned as forbidden. Woman on the past centuries is forced to live in shame because of their natural desire. Nosferatu freaked the society out, making a point to my opinion which Nosferatu is a representation of women's repressed desire.
The movie progressed well. I love how Willem Dafoe's character assuring Ellen that this is not her fault, a good representation that what she has is natural and there's nothing to feel wrong.
I'm giving this four because the movie is too quick paced, there's a lot of potential missed because of this.
