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: Haven
Adaptation Expansion: The show is based off a Stephen King mystery novel called "The Colorado Kid." Vince Teagues is a reporter, and the Colorado Kid is a mysterious appearing of a dead body several years before. That's about where the similarities end. Almost In Name Only.
Complete Monster: Harry Nicks, the Troubled in "The Farmer", illegitimately fathered dozens of kids through a sperm bank so he'd have a large supply of healthy organs. He did this before the Troubles kicked in, so this was premeditated. He has a family, which could have provided a justification if his victims weren't far older than they are, and if he hadn't tried to go after his oldest son as soon as that plan failed. In the end, the only thing he cared about was preserving his own life, and as a result he was directly or indirectly responsible for at least a dozen deaths. His behavior is partially excusable by the fact that the actual need to steal organs appears to be a compulsion that drives even those who know nothing their Trouble, but this guy still knew and prepared for it.
Fan Nickname: "Fraudrey" for the second Audrey Parker who showed up at the end of season 1.
Ironically, it turned out that Fraudrey was in fact the REAL Audrey Parker and the first one is the fake!
Harsher in Hindsight: In-universe. Nathan's rage against Duke (with repeated references to his inability to feel) in "Harmony" feels even angrier after he reveals in "Sins of the Fathers" that he blames Duke for the return of his Trouble.
Unfortunate Implications: Averted. When Duke Crocker, Caucasian, introduces Evi Crocker, a black woman, Audrey initially states that she didn't know he had a sister. Turns out, she's his wife. Though, given it's Duke, picturing him as married might be the bigger stretch.
