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.
Audience-Alienating Premise: It's a film about the real-life torture murder of an innocent teenage girl at the hands of her foster mother and various children. Does that sound like a movie you want to watch, want to have watched, or even a movie you can get through without feeling overwhelmed?
Fridge Horror: Jenny having to witness her older sibling's torture murder. That's going to haunt her.
Children and teenagers: Your foster parents want to torture you to death.
Parents: Don't trust anyone to take care of your children, unless you want them to suffer undeserved, cruel, and dragged out deaths.
Tear Jerker: If you have any sympathy for Sylvia at all, expect to cry during the torture scenes.
Sylvia's Dying Dream of escaping and reuniting with her parents, who tearfully apologize for leaving Sylvia to live with Gertrude. It gets worse when it's revealed to be a dream and that Sylvia is dying. You knew the escape scene wouldn't last, but damn, how you wanted it to be real.
