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.
Complete Monster: Joe St. George. In the film he's introduced by smashing Dolores' back with a log, threatens to kill her after she tells him that she won't put up with his abuse anymore, stealing their daughter's college funds Dolores worked hard to build up, and is eventually revealed to have sexually abused their daughter. It's no wonder that Dolores takes Vera's advice to plot his death and make it look like an accident by having him fall down a hidden well in their yard.
Jerkass Woobie: Vera is gradually revealed as one. Early on, Dolores notes about her employer demonstrates "three kinds of bitchiness", the last variety stemming from how she was an old, disabled woman trapped in her house. She also is visibly depressed by how distant her children are, most notably during the eclipse when she's convinced they'll return to Tall Island to see it with her, only for them to not show up. It's made even worse when it's revealed that her children died many years before in a car accident, and Dolores hypothesizes that Vera was trying to convince herself that she could will them back to life. Ultimately, this leads to Vera running in a panic and falling down the stairs and electing to die rather than suffer anymore from her "dust bunny" hallucinations and the grief of her lost children.
Nightmare Fuel: The "dust bunnies" appear to be nothing more than a bizarre hallucination experienced by an old woman. However, Dolores sees them in a dream and gets an idea of how terrifying they really are, especially when one bears Joe's face.
Dolores' murder of Joe is appropriately laced with Nightmare Fuel. The crowning moment goes to how despite being injured by the fall, Joe manages to crawl out of the wall and grabs Dolores' ankle, trying to pull her down with him, all while grinning like a maniac. Afterwards, she's haunted by the memory of his call. "Duh-LOR-riiiiiisssss..."
Squick: The scene wherein Vera deliberately shits herself and flings the stuff all over the room, in order to spite Dolores
The Woobie: Dolores and Selena. Dolores is a victim of physical abuse by the hands of her alcoholic husband, and struggles to help her daughter who suffers from depression and alcoholism after her sexual abuse by her father. After the accidental death of Joe, the two are constantly harrased by the neighbourhood and police day and night, forcing Selena to leave her home and leave Dolores to stay behind and serve her snobbish employer, Vera, as a maid. Dolores' life goes downhill once again when Vera tries to commit suicide by tumbling down the stairs and finds herself accused of murdering her employer.
