- In The Worst Witch it's explained that it's tradition for the teachers and pupils to wear their hair loose at the Halloween celebrations. In season 1's Halloween Episode, this doesn't happen except for Miss Hardbroom. In season 2 it's only implied to be Halloween and there's no reason why all the girls are wearing their hair down for the celebrations. Especially since they're normally only ever shown with it down when they're in their nightgowns.
- Power Rangers has had a couple of unexplained holdovers from Super Sentai:
- In Lightspeed Rescue, Diabolico and Olympius have a rather strange death scene where after they explode, a demon face shoots out of them, screams and explodes. This is because in the Gogo V version of this scene, the ghost of Bansheera's counterpart Grandienne was possessing them and died with them (this scene was Gogo Vs' final battle).
- In Gekiranger and Jungle Fury, monsters come in either alive (most of the major villains) or undead (most of the monsters-of-the-week, created from undead Mooks called Rinshi who are upgraded, gaining the ability to turn into the Monster of the Week at will) and have different deaths depending on this; live monsters get the standard fiery explosion, while undead freeze into statues and explode into dust, shattering just like the Rinshi they're made from. In the two-part premiere, the first Monster of the Week appears to die with the standard explosion multiple times, but isn't dead for real until he shatters. The difference is, Jungle Fury keeps several stories much the same as Gekiranger but doesn't make it especially clear when a monster is not a Rinshi Beast. Usually it doesn't matter much (It's not spelled out why Phantom Beasts and Grizzaka's underlings do not turn to dust in either version, but there's no reason to think they're Rinshi to begin with.) However, in one episode, The Starscream Naja has "life talons" that can restore him from near-fatal damage and resurrect others. He tries to tempt Camille with this. In Jungle Fury, it's not clear why that would appeal to her. If he joins her, they'd have "power over life and death," but only for as many resurrections as Naja has Life Talons; by the final We Can Rule Together speech at the climax, that's three. So not much temptation there. In Gekiranger, on the other hand, we get a detail that was left out of JF: Mele (Camille) herself is a Rinrinshi (Rinshi Beast), and talons from Braco (Naja) can make her truly alive. That is why it's so tempting. (It's also why, when he uses his first talon to save himself from Camille's poison, he instantly changes from Rinshi form into monster form, never to take on Rinshi form again: in Geki, it's the first clue of what the talons can really do; he was no longer a Rinshi. It's also the reason why the two monsters he resurrects explode like monsters in other seasons when destroyed; they are also no longer Rinshi and so don't die like Rinshi. The talons' ability to make you not a Rinshi anymore are an important detail when a normal explosion instead of a Rinshi death meant the monster was still alive three or so episodes previously.)
- Operation Overdrive inverts this; In Boukenger, Gaja's Mooks, the Karths ("Chillers" in OO) are often seen being used by other villain factions without explanation. The OO episode "Just Like Me", which features one such battle from the Sentai version, has Flurious' flunky Norg bring "Chiller stones" to Moltor, which he uses in the fight against the Rangers.
- In Gaoranger, Duke Org Ura is destroyed the first time when Shirogane charges at him and impales him on the Gao Hustler Rod. In Wild Force however, the impalement is cut out, so it looks like Merrick just destroyed Nayzor by shoving him.
- Dora Goblin from Zyuranger devoured the souls of children. Gnarly Gnome from Mighty Morphin' Power Rangers, however, did not, which led one to wonder what were all those balls of light that flew out of him when he exploded.
- Season 2's Mirror Maniac's mirror face is shattered for no explicable reason when he goes big. His Dairanger counterpart, Master Mirror, got his face shattered by Shishi Ranger prior to that.
- Also from season two is the Showbiz Monster, who for no apparent reason dissolves into light when defeated instead of exploding. This is because while Showbiz Monster was just a standard Monster of the Week, his Dairanger counterpart Media Magician was actually a sympathetic character, and thus got a gentler death.
- A minor one from Power Rangers Dino Charge; in Zyuden Sentai Kyoryuger, the villains' plans revolved around gathering human emotion, specifically anger, joy and sadness. This element has not carried over to Dino Charge...and yet almost all the monsters still have a happy, sad or angry face somewhere on their bodies.
- In Zeo, Rita accidentally creates a monster from a purse...which is inexplicably not only her strongest creation ever, but possibly the strongest Monster of the Week in the entire franchise, even able to shrug off the finisher from the Zeo Ultrazord. In the Ohranger-Kakuranger teamup movie it comes from, there actually is an explanation for this: it's not that it's incredibly powerful, but simply that as a magic-based Kakuranger monster, it's impervious to the Ohranger's technology-based weapons.
- Inverted in Power Rangers Time Force; the first episode of Mirai Sentai Timeranger has a bad Unexplained Recovery moment when the Timerangers are trapped in a crashed ship which explodes with them on it...and are inexplicably uninjured afterwards. In the corresponding Time Force scene, Trip frees himself and gets the others off the ship before it blows.
- Warmax from Power Rangers Mystic Force is a member of the dread Barbarian Beasts... who gets exploded by one hit from the Mystic Minotaur, and that's that. Except in Mahou Sentai Magiranger that wasn't that; it turns out the body was just a puppet and the sword was the actual monster, which then possesses Magi Green and wreaks havoc. This part of the episode was not adapted into Mystic Force, likely due to the large amount of unmorphed footage.
- Inverted in an early episode of Masked Rider, where a trio of skull faced monsters are pointed out to have a weakness to water, and Masked Rider is able to destroy them by tackling them into a lake. This weakness is not mentioned in Kamen Rider BLACK RX, where going in the lake just makes them explode for no apparent reason.
- Legend of the Seeker: In the first book, the title of The Book of Counted Shadowsnote refers to how the boxes each cast a different number of shadows when they're in direct sunlight. In the series, the boxes display no such quality, but the book keeps its title.
- The pilot of Dirk Gently includes two notable scenes from the original novel: Richard Macduff stopping a message from reaching his girlfriend (by stealing her laptop rather than stealing a tape from her answering machine) and Dirk explaining about his involvement in the Schrödinger's Cat experiment. In the book, the first scene happens because Richard is unknowingly possessed, and the second is Dirk testing whether Richard is thinking logically enough to spot he's talking nonsense. Neither of these explanations come up in the series. (Although to be fair, series!Susan doesn't live in a high-rise flat, so climbing in her window isn't quite as much of an irrational action that needs explained and tested.)
- The Flash (2014): Speedforce is mentioned several times in the series but it's never really explained what it really is, leaving those who don't read the comics terribly confused. In the comics, it's explained that the Speed Force is a sentient extra-dimensional energy field that grants people like Barry enhanced speed and reflexes while protecting them from the effects of friction and entropy; it provides a cozy Hand Wave for how the Flash's powers are able to twist the laws of physics so much.
- American Gods (2017) keeps Laura Moon's pet name "Puppy" for her husband Shadow, but doesn't explain why she calls him that. The novel explains that she always wanted a puppy, but couldn't get one because her and Shadow's apartment lease didn't allow pets; Shadow tried to cheer her up by jokingly saying that he could be her puppy, pointing out that he could do anything a puppy could. note It can come off as a bit more condescending and mean-spirited in the show, since it implies that Laura sees Shadow as more of a pet than a husband.
- In Hogfather, the Librarian of Unseen University has written a letter to the Hogfather, with Ponder Stibbons noting that he can do this even though he's an adult because the rules are different for orang-utans. The Librarian doesn't appear in the TV adaptation, nor is his species mentioned, so it's not particularly clear why the wizards expect the Hogfather to show up in the library, or why this prompts Ridcully to wonder if he'd deliver to apes before humans.
- In his original appearance in Silver Age Superboy, Mon-El was an amnesiac who Superboy assumed must be Kryptonian since he shared all his powers. Clark therefore named him "Mon-El" based on his own Kryptonian name. Even once he remembered he was a Daxamite named Lar Gand, he continued using Mon-El as his superhero identity in Legion of Super-Heroes. In Supergirl, Mon-El is his actual Daxamite name (Lar Gand is his father), and the fact this doesn't just sound Kryptonian but specifically like Kara's family isn't even commented upon.
