These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mary Reilly
Nightmare Fuel: Hyde's whispered "Mary Reilly" used as the tagline for most of the trailers...
Mary's father, period, but especially the quiet, almost jocular way he talks to her when he's about to torture her or worse.
One-Scene Wonder: Glenn Close actually has about three scenes, but you can tell she has great fun in bringing her character (the madam of a brothel) to life.
Squick: The scene in the slaughter houses. Also that little girl in the brothel. And the room in the brothel. Actually, quite a few scenes in the film are comprised of this.
