I started reading Doppelganger by Naomi Klein for the discussion of disinformation, but I stayed because it’s secretly a great analysis of horror movies and books.
I would have read this much sooner if I had known it was going to involve exploring doubles and imposters in scary stories all the way back past Freud, to fairy changelings, golems, and theology about the duality of soul and body.
Most horror movie analysis I’ve read picks one theme (racism, feminism, imperialism, or whatever) and looks at all the ways that has been expressed in horror.
It’s a fun change to read a book that picks one image (the double) and looks at all the horrifying themes it can express
