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.)
Fridge Brilliance: Donald Faison played the exact same character when he appeared in Magic Joel (season 1) and Rumour Mill (Season 2); that's why he wanted to become a magician's assistant when he appeared in the mortal realm in Magic Joel. Likewise, Lindsay Sloane was the same character in Sabrina and in Bring It On. She was so sick of being a victim that she dyed her hair and changed personality entirely when she moved. That or she accidentally drank a confidence/ambition potion.
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.
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.)
Jumping the Shark: Widely believed to have jumped either when Sabrina went to college or when both Hilda and Zelda were no longer in the show.
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.
Nightmare Fuel: An early episode had Zelda and Hilda create a boy for Sabrina to date out of 'Man Dough.' At the end of the episode, he expires and explodes into globs of dough off-screen. After the other characters leave, his mouth reappears on a blob and excitedly says 'Man, what a great night!' (An ingredient mix-up made him overly enthusiastic).
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.
This is hilarious considering Sabrina actually ends up with the fan-favorite, Harvey, in the series finale.
In season 4, Dreama for Valerie and Brad for Libby.
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.
Tear Jerker: The Season 6 episode "The Whole Ball of Wax", at the end when it looked like Sabrina's mom died from being next to an iron.
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.
