YMMV / The Taking of Deborah Logan

• Complete Monster: The entity possessing Deborah Logan is revealed to be the ghost of Dr. Henri Desjardins, who in life was a child murdering physician. Desjardins engaged in a series of cannibalistic murders with the intention of enacting an ancient ritual that required the sacrifice of five young girls, believing it would grant him immortality. Desjardins was eventually killed by the titular character when she found out that he was planning to use her daughter Sarah as the fifth sacrifice. As a spirit, Desjardins gradually possessed Deborah, causing her mind to deteriorate. Once taking full control over Deborah's body, Desjardins abducts a young leukemia patient named Cara, intending to finish the ritual he failed to complete, injuring and killing anybody who stands in his way, including the town sheriff, and then attempting to swallow Cara alive before he is seemingly destroyed. The ending, however, heavily implies that Desjardins continues to live on inside Cara's body.
• Fridge Logic: Deborah found out Desjardins was planning on murdering Sarah by overhearing a phone call on her switchboard. So who the hell was Desjardins spilling all his plans to over the phone and why didn't they go to the police?
• Spiritual Adaptation: The story seems to be inspired by The Case of Charles Dexter Ward with the possibility of it ending a whole lot worse for all protagonists involved.
