** ''Series/TheFlash2014'' to Franchise/TheFlash: It's about a man named Barry Allen who gains SuperSpeed after being hit by lightning in his lab and fights crime in a red suit. At first the show is a Type 2, almost a Type 3, to the ComicBook/TheNew52 rebooted version of the character (itself a Type 2 to the comics proceeding it), but it delves further down as it introduces characters from the earlier ComicBook/WallyWest era of comics, but each one is increasingly InNameOnly. Each season is almost recognizably lifting from a Wally West storyline, but makes such heavy changes to the story and characters (such as [[Characters/TheFlashHunterZolomon Zoom]], Jesse Quick, Savitar, and others), not to mention the fact they're re-written to work around Barry Allen instead of Wally West, while Wally himself is pushed out of the show without ever graduating out of the Kid Flash mantle, never mind the fact he was heavily retooled in the first place. The show similarly adds a 'team' around Barry, using Vibe and Killer Frost (and later, Elongated Man), but who (with the exception of Elongated Man) have no prior history working with the Flash and in the show have their personalities, backstories, and even their powers changed and altered. [[ArsonMurderAndJaywalking They also make Barry]] the [[NotBloodSiblings foster brother of his love interest Iris West]] and created a completely different character as her father to act as a ParentalSubstitute to Barry.

* ''Film/SupermanTheMovie'' gets most of the fundamentals right, but alters quite a few aspects compared to the comics of the time: the Kryptonian aesthetics and Lex Luthor's personality are completely changed, Superman and Lois are softened, the whole concept of Superboy is cut in favor of having him debut as an adult, a lot of the weirder ideas are toned down or removed, and there's a few {{Canon Foreigner}}s. Complicating this somewhat is that a number of aspects of the film [[RetCanon made their way back into the comics]], to the point that when compared to some runs, it looks closer to a 3 or even a 4.

* The 2011 LiveActionAdaptation of ''Anime/RanmaOneHalf''

* ''Literature/TheChroniclesOfNarnia'' is somewhere between 3 and 4. The first film is probably a 4 while the other two films are closer to 3.

* The Creator/MichaelBay ''Film/{{Transformers}}'' films seem to have started life as an adaptation of the franchise's initial "[[Franchise/TransformersGenerationOne Generation 1]]" incarnation, with far more elements being taken from there than every other series combined. If that is to be taken as the source, then many characters have had their names changed or their personalities altered, the aesthetic is far different from any prior series, with quite a few characters being [[YouDontLookLikeYou unrecognizable in appearance]], and many concepts and characters are [[CanonForeigner entirely invented.]] Consequently, though G1 has its fair share of divergent continuities, the franchise as a whole considers the films to be their own "branch."

* ''Manga/BlackButler'' season 3 and "Book of Murder" {{OVA}}

[[folder: Level 3: PragmaticAdaptation]]

* ''Anime/BlackButler'': Season 1 (arguably a 2.5 for the anime-original ending, but it's still very close in tone and theme to the manga and the previous 3/4 of the anime are very faithful to the manga).

[[folder: Level 2: RecognizableAdaptation]]

* ''Manga/BlackButler II'': The entire season is anime-original, having no basis in the manga.

* ''Film/ScottPilgrimVsTheWorld''

* ''Film/WorldWarZ''

* ''WesternAnimation/TheSuperMarioBrosMovie'' has a lot of changes to how certain characters and power-ups work in the [[Franchise/SuperMarioBros games]], but is overall accurate to the series.

* ''WesternAnimation/TheSuperMarioBrosMovie'' has an origin story plot that had only been explored in the

* ''WesternAnimation/HowToTrainYourDragon'': All three films. One of the few cases of an unfaithful adaption doing better than its source material.

* ''WesternAnimation/TheSuperMarioBrosMovie''

** On the low-end of the scale, ''Film/SpiderManHomecoming'' is a Type 2 that almost borders on the Type 1; it has Peter still as a young teen after Civil War (he was married and in his 20s when this happened in the comics), and he attends a charter school designed explicitly to nurture scientific minds when typically Peter attended a public school. He was bullied for his intelligence and had no friends in school originally, whereas here he's got several and is instead admired for his intelligence as he's a valued member of the school's academic team, while Flash Thompson, typically a popular jock archtype from an abusive household, is a spoiled rich kid academic, who's obnoxious behavior makes ''him'' the unpopular outcast. In the post-MCU Civil War world, Peter is a loyal sidekick to ComicBook/IronMan and longs to join him in the Avengers, whereas in the comics Peter has cut ties with Tony out of disgust over what he did during the war as well as failure to protect his family. Vulture's backstory is ''similar'' to his comic counterpart (being a businessman screwed over by richer businessmen, in this case Tony Stark), but here he's upper-working class/lower-middle class who's more a leader than an inventor, whereas typically he was a well-off inventor and scientific genius but was too sociopathic to lead others.

** ''Film/SonicTheHedgehog22022'' uses the largely original setting and lore of ''Film/SonicTheHedgehog2020'' (itself a Type 1.5) but adapts it to the plot of ''VideoGame/SonicTheHedgehog2'' and ''VideoGame/Sonic3AndKnuckles'' with elements of ''VideoGame/SonicAdventure'' sprinkled in.

** ''Film/SonicTheHedgehog22022'' uses the largely original setting and lore of ''Film/SonicTheHedgehog2020'' but adapts it to the plot of ''VideoGame/SonicTheHedgehog2'' and ''VideoGame/Sonic3AndKnuckles'' with elements of ''VideoGame/SonicAdventure'' sprinkled in.

* ''Series/TheLastOfUs2023''

* ''Anime/DeathNote''

* ''Series/TheLordOfTheRingsTheRingsOfPower'' covers the Second Age, and took a lot of freedoms from the source. The Tolkien Estate forbade Amazon to adapt anything that has to do with ''Silmarillion''. Amazon paid the Estate with $200 million to secure the rights to the ''Literature/TheLordOfTheRings'''s appendices about the Second Age. In the same time, the estate of J.R.R. Tolkien allowed time compression, and gave Amazon plenty of creative freedom for new characters and plots, but they were not allowed to contradict or change anything about the age in which the original story takes place.

* ''Literature/AnimalFarm'': Both film adaptations stick fairly loyal to the original book besides some minor character changes or omissions. The DownerEnding of the original book however is expanded in both takes to [[AdaptationalKarma have the pigs get their comeuppance]], likely to mirror the gradual downfall of the Soviet Union they were based on after the book was written.

* ''Series/TheWheelOfTime2010'': Like ''The Witcher'' mentioned below, it's most similar to the source material in the first few episodes, with the changes to every part of the story and characters quickly mounting up with each new episode, some even having more [[AdaptationExpansion added or expanded material]] than storylines actually adapted from the books.

* The first ''WesternAnimation/{{Shrek}}'' film is somewhere between a Type 1 and Type 3. The film borrows very few elements from the William Steig book save for Shrek himself and Donkey (who only appeared on one page), but a picture book does require some major AdaptationExpansion to make it viable for a feature length film.

* ''Film/WhoFramedRogerRabbit''. Though it overlaps as a Type 3 in some aspects.
