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.
Complete Monster: The child-murdering Winifred Sanderson, who seems the only one truly evil of all three sisters (the other two are too stupid to really count). Though Winifred, like the other two, is Played for Laughs most of the time, there ARE moments in which she is truly frightening.
Binx, full stop. Heaven knows he's far more interesting than anyone else in the cast barring the witches, themselves. He's also most sympathetic character, given his nightmare fuelish backstory.
Billy is a more notable example, in that he is a much smaller role who tends to be well-remembered and a favorite of fans of the film.
Four Temperament Ensemble: Winifred is choleric, Sarah is sanguine, and Mary is melancholic/phlegmatic
"Funny Aneurysm" Moment: When Sarah Jessica Parker did Who Do You Think You Are she was very disturbed to discover that one of her ancestors was accused of being a witch in Salem, MA. Before learning about her ancestor, she says she would rather have her being accused then doing the accusing. Luckily the witch craze effectively ended one month before her trial.
Hilarious in Hindsight: When Max rescues Dani from certain death by the Sanderson Sisters, he says, "I know one kind of power that you don't have!" (or something like that), and Winnie asks, "And what is that, dude?" before he replies with, "It's Daylight Savings Time," followed by the turned-on car lights pretending to be the sun that harms them. Of course, considering that it was a joke back in 1993 (when DST ended on the last Sunday of October in the U.S.), the new U.S. Daylight Saving Time rules weren't around until 14 years later, when DST now ends on the first Sunday of November from 2007 onward. Of course, the joke now still works only if Halloween happens to fall on the day before the first Sunday of November (i.e., Saturday, October 31).
Memetic Mutation: Long after this movie left theaters, you couldn't use the word "amok" without somebody chiming in with Sarah Sanderson's sing-songy "A-MUCK, a-MUCK, a-MUCK, a-MUCK!"
Nightmare Fuel: The book, zombies, immortal black cats really a boy denied entrance to heaven and soul sucking witches.
Older Than They Think: In the 1964 short Looney Tunes short "Bewitched Bunny", Hanzel and Gretel turn to Witch Hazel and say, "Ack, your mother rides a vacuum cleaner" before fleeing.
Squick: Tastefully averted. Emily Binx gets all the youth and vitality drained from her at the beginning of the film - but she slumps over in death, leaving only her gray hair visible. One can only imagine what her face looks like.
Tear Jerker: Admit it - you cried when Binx died, too.
The Woobie: Say what you will about the film, overall, but you just can't help but feel very sorry for poor Binx. The poor kid fights for all his worth to save his little sister, just to fail and then endure a Painful Transformationinto a cat. Then he gets rejected by his father who he was trying to communicate with in his hour of grieving. Finally, and this is the juicy bit, he spends the next few hundreds years, alone, with only his self-appointed duty in keeping the witches from coming back to give him purpose, but otherwise wandering aimlessly through his own personal, eternal hell. The only thing that averts this from being a full on And I Must Scream is that he somehow relearns how to talk as a cat.
