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: Sabrina the Teenage Witch
Adaptation Displacement: Not only do many people not know the show was based on a comic, or even that Sabrina is from the same comic family as Archie, many elements and characters from the show were used in later versions of the comics (such as Salem originally being human.) There was also a 70s Saturday morning cartoon (Sabrina and The Groovie Goolies) and a TV-movie before the show that no one remembers.
Anvilicious: Many of the magical illnesses or other Plot Coupons in the TV series were based around obvious Aesops. (Too vain, turn your boyfriend into wolf-boy. Try to use magic to get your rival out of your hair, nope, now you're tied to her.) Lampshaded by Sabrina. (See Freudian Excuse on the main page.)
Truthfully a lot of the two aunts' spells border as malicious Mind Rape, usually tormenting Sabrina or a helpless mortal with them as payback for some petty act (they once gave Sabrina a nightmare convincing her she would end up a homeless bum for not taking her practices seriously enough, and doomed a teacher to permanently work in the job he hated for being rude to them. One episode also had them so vehement on punishing Sabrina they stole all of Salem's rightfully earned magic dust to make it work). This is always presented as fantastic karma, but borders on vindictive Moral Myopia.
An early episode has Libby fall in love with Sabrina's date (an Artificial Human made of 'Man Dough'). At the end of the episode, he expires and explodes, leaving Libby wondering where he went. During the credits, we see her on the phone, trying to file a Missing Persons report, but is laughed off by the police. There's no joke or punchline, it's just the police refusing to search for a (for all they know) missing teenager.
Girl-Show Ghetto: Inverted. To cash in on Sabrina's popularity, ABC produced two Urban Fantasy series, Teen Angel and You Wish, though with male protagonists. Both shows ended after a season, while Sabrina lasted for years and even had a few spin-offs.
In season three, to stop Valerie from becoming a cheerleaderr, Sabrina tells her that no cheerleader ever went on to become president. Two years later, George W. Bush was elected - and he had been a cheerleader.
Also Valerie's desire to join the cheerleading squad becomes absolutely hilarious - bordering on Casting Gag - if one watches Bring It On where Valerie's actress Lindsay Sloane plays head cheerleader and Alpha Bitch Big Red.
Hallie Todd's episode as Cousin Marigold ends with her attempting to bond with her new boyfriend's kids. Hallie Todd guest starred in an episode of Two of a Kind where she tried to do the same thing - and failed miserably.
Jerkass Woobie: Try to resist the impulse to hug Amanda at the of the Season 7 episode "Bada-Ping", when she realizes she's the cause of Sabrina's predicted death. (A prediction that, thankfully, never comes to pass.)
Mis-blamed: The show was constantly accused of being a rip-off of many similar shows during its run, most notably Out of This World and Bewitched. Despite popular belief, Sabrina was originally a comic book character in the 1960s, and predates Bewitched.
To its credit, Sabrina was inspired by Bell Book And Candle, which was also the inspiration for Bewitched. The idea that a witch would become mortal if she fell in love with a human, which was mentioned in the first comic, and later dropped entirely, was directly taken from the movie.
In Japan, the show was often mistaken as a rip-off/remake of I Dream of Jeannie, due to the shows being dubbed "Cute Witch Sabrina" and "Cute Witch Jinny" respectively. Funnily enough, Sabrina in the Filmation cartoon was dubbed by Akiko Nakamura, who was also Jeannie's dub voice.
One-Scene Wonder: Aunt Vesta only appeared in one episode, but Raquel Welch was extremely memorable, and the character was referenced unseen in later seasons.
Barbara Eden as Aunt Irma, who only appeared in the last season. Supposedly, she would have become a recurring character if the show had lasted.
Josh for Harvey. Whereas Harvey and Sabrina had a fairly healthy relationship, Josh's relationship with Sabrina was all about her giving and him just taking. He was going to move to Prague without considering her feelings, is obsessively jealous, chews Sabrina out for embarrassing him at work and never supports her plans or wishes.
Morgan for some, due to how unlikable she started becoming as the show progressed.
Show, Don't Tell/Shocking Swerve: The first couple of minutes of the first episode of Season 7, which very clumsily explained the resolution to the cliff hanger ending of Season 6.
Strangled by the Red String: A straight example in the final season that ultimately evolves into a Deconstruction. Sabrina falls for Aaron in his debut episode so much that she uses magic to find out what his flaws are. They hook up at the end of the episode and for the rest of the season simply act as a couple that's been together for years, rather than developing slowly. It's never explained why Sabrina literally makes room for him in her heart. However cracks start to appear as Sabrina initially thinks his proposal is a trick caused by the Monster of the Week and accepts reluctantly. The rest of her actions during their engagement come across as straight-up denial more than anything else. Finally when her wedding day comes, she gets cold feet and dithers between that and denial. She and Aaron ultimately agree to call off the wedding.
They Just Didn't Care: Many fans felt this way about the show forgetting that Sabrina only had to wait two years so she could see her mother again, as opposed to never being allowed to see her for the rest of their lives.
