Opera playing in the background of the villain’s scene. Opera fans, in my experience, are not always serial killers and sociopaths. Sometimes, but not always.
Women in power portrayed as emotionless bordering on cruel. I.e. the Dragon Lady.
The use of children as victims because it isn’t p.c. any more to constantly portray women being victimized, but kids can’t speak up to protest their portrayal, so that makes it OK. NOT!
Increased use of landscapes and vistas in murder mysteries, shamelessly pilfered from Scandanavian shows but welcome nonetheless. The beauty of nature helps contrast and give time to process the violence of the story.
The celebration/normalization of weird. Because I’m a freak, you’re a freak, and we’re all just freak, freak, freaky. Yay.
The ability to binge. This is the Easter Play come full circle. One must pause only to get food, walk the dog, or go use the pissing pot. This is how we are meant to absorb stories. To dive in and let them wash over us. To read them by the fireside as the days pass away. To marvel at them, ponder them, and shout out when they finish: AGAIN!
