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.
Alternative Character Interpretation: At the very end when Louis buries Rachel in the burial ground, is it simply a case of him being driven mad with grief, leading to him repeating his mistakes all over again? Or deep down, does a part of him know that Rachel will simply become a murderous abomination just like Church and Gage did, and is doing it to get her to kill him in some sort of penance for what his actions resulted in, performing a sort of Suicide by Cop if you will?
The Woobie: Ellie Creed. At the end of the story she's sedated in the hospital, perhaps driven half-mad from unheeded psychic warnings, her brother is dead, as is her mother, and her cat, and in the movie her father (though it's a given that he'll also die soon in the book). And all this at the age of six...
Jerkass Woobie: Louis, who just won't learn his lesson about letting dead stay dead, but you can't help but pity him anyway.
Zelda, somewhat, too. She wasn't exactly nice, but she was a little girl in HORRIBLE PAIN and nobody could do anything about it.
Uncanny Valley: People and animals brought back by the burying ground usually have this effect on the living. Even for those that aren't in the know, there's something just not right about them. Louis describes a time when Church jumped into a visitor's lap, and they almost immediately pushed the cat away, somehow sensing that there is something inherently wrong about the cat. Jud's story about Timmy Baterman being brought back shows that it's even stronger with other humans.
