about to watch Crimson Peak
crimson peak spoilers, if vague
The film deploys the cliché of sexual deviance as the sin of the aristocracy. Indeed, it presents all the horror as deriving from that original sin. There's a brief moment that acknowledges that deviance itself as having an origin, but it's brushed past. I think a Crimson Peak that developed that question further would have been more interesting to me, although I'd still have had mixed feelings.
this is the only feature film directed by Guillermo del Toro that I have not yet seen. although I should rewatch Pan's Labyrinth and The Shape of Water since I didn't watch them super recently.
