I definitely think there's Something (TM) to say about the portrayal of "off-human" characters in modern media adaptations as having (particularly facial) deformities and/or learning disabilities.
Robert Louis Stevenson was fully like "this is my OC, Hyde, who represents the impact of a complete apathy toward your fellow man. There is nothing extraordinary about him except that his rancid vibes make people uncomfortable which adds to the core theme of the role of morality in humanity, so its really important that he's physically normal so the audience can recognise that it's what's inside that's most important," and every film adaptation was like "mmkay. Yeah, no, I've got it. We can show that he's evil by using prosthetics and making him non/semi-verbal, which, as we all know, are the True Measures of Evil."
