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.
"Blast this pen, blast this wretched, wretched pen!"
Misaimed Fandom: Many fur fans actually like Cruella, especially the animated version, for her huge fox coat. And a lot of the mentions of fur, like sleeping between ermine sheets in the book, often just seem like a sybaritic Pretty in Mink.
Nightmare Fuel: Cruella ("-De Vil"), Cruella ("-De Vil, if she doesn't scare you, no evil thing will..."). And more.
Likewise, the part where the dogs are hiding in the coal shed and suddenly Cruella is right there at the window, driving past really slowly and glaring in at them. It gets even worse when, shortly thereafter, this is repeated with Cruella going the other way.
A very important example that combines with Fridge Horror. She's ordered her henchmen to kill puppies and in the most painful ways possible to have them skinned into a fur coat which is scary enough; now, consider the following: it's implied they were her regular employees, so they do work for her all the time, but acquiring fur illegally — by stealing and killing puppies — IS the only work she ever gives them, and we are shown that she already had about fifty fur coats made up by the time the police caught her. Oh, God, those poor hundreds of puppies...
Of course, all but Pongo and Perdita's litter were actually bought and paid for. Doesn't excuse the killing of those poor puppies, but it does seem to lighten the blow just a wee bit.
Just look Pongo and Perdita's faces when they are facing off Jasper and Horace. They don't look so sweet anymore...
Sequelitis: Patch's London Adventure makes this the third version to have a sequel.
But as far as Disney sequels go, it's one of the better ones.
Tearjerker: In the sequel, when Thunderbolt reveals his lie, Patch is devastated. "But you said you'd help us…." Just how his voice breaks on that line; he'd trusted Thunderbolt, he'd thought he would know what to do.
Viewer Gender Confusion: Pepper gets one speaking line during the entire film and her voice led many people to believe she was male.
The Live Action Remake and its Sequel
Broken Base: The first live-action movie is a base breaker on its own compared to the animated version, but the sequel is even more of one. Was it better, worse, or on the same level as the first movie?
Family-Unfriendly Aesop: You should never give a second chance to anybody. He will most probably become evil again if he's anywhere near the Big Ben, anyway.
Fan Dumb: After the release of the live-action version, people rushed to get Dalmatians as pets. Dalmatians are highly energetic and need plenty of room and time for exercise, and are prone to hearing problems. Many of the Dalmatians adopted during this craze ended up surrendered to shelters or dumped.
Even the trailer to the sequel has nightmare fuel! It starts out all quaint and innocent with a puppy and a catchy theme song, but it's interrupted by lightning and shifts to Cruella, who cackles ominously and says, "Surprise!"
Villain Decay: Cruella was noticably less menacing in the second live action movie than she was in the first.
What the Hell, Casting Agency?: It may not be six-time Oscar nominee Glenn Close's most profound role, but she makes a really good Cruella and it would appear she's having a ball hamming it up.
The TV Series
Anvilicious: While the TV series has An Aesop in most episodes, they never jammed them into your head. The episode "Smoke Detectors"note The pups have to try and get Cruella to stop smoking so she can move back to her house instead of living with them because the fire from her cigarettes burnt down parts of her house from smoking and sleeping at the same time, on the other hand, falls right under this.
Big Lipped Alligator Moment: The sudden and one-time uses of a studio audience laugh track in "You Slipped a Disk" and "Chow About That?"
Creator's Pet: Spot is mostly disliked because she's a main character and Ensemble Darkhorse Two-Tone isn't (or Patch, thus filling out the four characterized puppies from the original book.)
Fridge Horror: One has to wonder if Dipstick's low intelligence might be the result of that flea infestation cutting off a lot of blood to his brain. Then again, a dog having that many fleas is disturbing in itself.
Jerkass Woobie: In the series, the episode "Coup De Vil" actually turns Cruella into one.
Several episodes of the series portray Cruella as a Jerkass Woobie / Jerk With A Heart Of Gold combination.
Memetic Mutation: "Yard sale? I love yard sales! Actually, I hate yard sales. Of course, the pros of a yard sale are the bargains, but the cons of a yard sale are that the items are used. Ick!"
Cadpig's comment about "day old pizza"
Moment of Awesome: The TV series had its fair share, but one in particular from the episode "Full Metal Pullet" has Spot being the only member of Lucky's group standing up to Lt. Pug after she was Picked Last out of everyone.
How many here didn't know Spot the Chicken was a female until her gender was actually mentioned?
The same could be said about Cadpig, since her voice and small size fit the requirements of the young boy character voiced by a female voice actress.
Villain Decay: Cruella in the TV series, who is still a greedy criminal who hates dogs but is more of a conniving cartoonish villain than the nasty piece of work she was in the films. Also, even after the events of the film (which presumably are still part of this canon in some form), nobody else seems to hate her as much as they should (except Roger).
Moral Guardians were likely opposed to the idea of vicious murder on kids' cartoon series.
The Woobie: This varies, but Rolly and Spot usually qualify for this.
The episode "Hog Tied" actually turns Dumpling into one pretty effectively.
