!!The book:
* {{Anvilicious}}, but SomeAnvilsNeedToBeDropped: The book takes several {{Author Tract}}s towards the end to smack the idea of "Go outside and run around in the fresh air, and if you think you're ill it'll make you ill and if you think you're healthy it'll make you healthy, and believe in the Magic!" But then again, [[SomeAnvilsNeedToBeDropped who can wholeheartedly argue with that kind of]] [[AnAesop Aesop?]]
* ItWasHisSled: On the first time through the book, Colin's existence is quite a shock.
* JerkassWoobie: Colin and Mary both, pre-CharacterDevelopment.
* PuritySue: Dickon, Susan, and probably Lilias. Still, it's not very noticeable, especially with brats Mary and Colin to balance them out.
* ToyShip: ''Three-way'' {{Toy Ship}}ping.
** TriangRelations: Type 11. Make of that what you will.
*** The 1993 film plays this way up. You can almost feel the U(non)-ST coming off of Dickon and Mary (swing scene particularly), and Colin flat out says he wants to marry her.
* UnfortunateImplications: "You're not dying! You just need to go play outside!"
** To be fair, the servants all acknowledge that Colin was legitimately sick several times in the past, but often ''threatened to fall ill'' in order to get his way. The difference was usually decided by whether he was throwing a tantrum, or quieter due to actual weakness.
** It's also fairly legitimate that their well-intended sheltering was making his disabilities worse. [[AccidentallyAccurate A modern physician may well have told them]] that living in a sterile environment was making him liable to allergies, and he needed physiotherapy exercises, not enforced immobility. (They still probably wouldn't expect such a dramatic cure, though.) And the point about his needing social contact and mental stimulation, however poor his health is, is perfectly valid.
** The 1975 version of the film also has several scenes in which Colin complains that fresh air makes him worse, despite the fact that his room is very stuffy. Sterile environment + stale air + heat = a recipe for disaster, so he may have become ill due to environment many of the times that his sickness was legit.
* ValuesDissonance: In 1911, the British Empire was in full swing, and it shows in this book. Indian people are referred to as "blacks" and they're considered less respectable than white people. The narration even refers to Mary having used violence against her servants in the past.
** Mary's abuse of the Indian servants, however, is meant to reveal that she is a spoiled brat. Martha also reprimands Mary for her racist attitudes when Mary becomes outraged after learning Martha thought she was "black" at first.
*** It's also quite clear that bringing up a small girl in the belief that she's inherently superior to those around her- even her caretakers- is what made Mary so dysfunctional in the first place.
** On a less serious note, Mary, a ten-year-old girl, is often and bluntly referred to as "ugly" by both the narrator and other characters and often to her ''face''. Also, compare the approving references to her getting "fatter" (i.e. healthier and less scrawny) with today's concerns with obesity.
** Mrs. Medlock, and even some of the more sympathetic characters like Martha and Mrs. Sowerby, also often refer to Mary as sour, contrary, or with adjectives that indicate a perpetually bad attitude. One wonders how much self-fulfilling prophecy played into her character.
** Also, this: "She used the wrong Magic until she made him beat her."
** More a case of SocietyMarchesOn, but we're supposed to see Mary- at least through Martha's eyes- as dysfunctional and hopelessly coddled because at the advanced age of ''nine'' she never goes anywhere by herself. In the same part of the world now, Mary would be at about the minimum age that children would start going out of sight of home without an adult.
* {{Wangst}}: Colin is like this until Mary gives him a good talking-to.

!!The various adaptations:
* CrowningMusicOfAwesome:
** The 1987 version uses Chopin's Nocturne in E Minor, Op. 72, #1 as its theme music.
** The 1993 film has some very beautiful theme music, too.
** The score for the 1975 miniseries? Yeah--freaking awesome.
** "Lily's Eyes" and the various Storms in the musical version.
* DesignatedVillain:
** The 1993 film ''and'' the anime series designate Mrs. Medlock as an overbearing caretaker, even though in the book her initial antagonism fades as the narrative progresses.
** The musical designates Neville Craven, a doctor who wants Colin to die so he can inherit his brother's estate. In the book, he is in fact a deeply caring man who took up medicine to help his older brother.
*** Granted, it's not quite stated, merely implied by an accusation from Mary. He's still the primary antagonist, though.
** The anime series not only does this to Medlock, but [[spoiler: creates a character for this: Max Hawkins. He actually turns out to be a decent person once we get to know him, but he ''was'' badly broken in the past and thus he can't forgive Archibald Craven for his BreakTheCutie experiences.]]
* DieForOurShip: The 1987 film has a bit of this outside of the story. Since the film makers made it so [[spoiler:''Colin and Mary aren't related'']], they had to get rid of [[spoiler:Dickon.]] The only way to do that was to kill him.
** The sequel to the 1987 version ''Back to The Secret Garden'' also does this when Dickon gets a fair bit of mention from Martha and Mary as he [[spoiler: died in the war before the end of the last film]] resulting in Mary and Colin [[spoiler: KissingCousins ending up married.]]
* The 1993 version gives [[spoiler: Dickon]] a HappyEnding, although the ShipTease between Mary and Dickon and Mary and Colin gets a more AmbiguousEnding.
* Speaking of ''Back to The Secret Garden'', Lizzie Buscana is a HeartwarmingOrphan who travels to Misselthwaite Manor from America at Lady Mary [[spoiler: Craven's]] request to take the place of one of the orphan's now living at the manor in desperate need of surgery at an American hospital. When Lizzie arrives she quickly gains two LoveInterests in the form of Robert and Steven, orphans who now live and go to school at Misselthwaite Manor.
** ShipTease ensues, particularly between [[spoiler: Lizzie and Robert]] the BelligerentSexualTension becomes more obvious over time to the point where EveryoneCanSeeIt.
* Lizzie's new friend Geraldine, a BitchInSheepsClothing who later turns out to be a JerkWithAHeartOfGold, actually spurs on the plot by encouraging Steven to take the blame for Lizzie when she steals her OrphansPlotTrinket, [[spoiler: the key to the Secret Garden]], from Martha Sowerby's desk drawer.
* Lizzie and Robert become [[spoiler: an OfficialCouple]] during their FetchQuest to find the [[spoiler: original door to the Secret Garden]] which was replaced [[spoiler: when Martha Sowerby was unable to find it after Mary left for America with Colin]].
* NightmareFuel: In any of the film adaptations, Mary walking through the house to find Colin can be deeply unsettling. The 1987 version takes this UpToEleven with scary music and a lightning storm raging outside the manor -- and let's not forget the cutaways to the light playing off of the dark, ugly statues.
** There's also the opening from that same movie, where Mary's wandering through a house where everyone except her is dead or dying from cholera, and she doesn't even understand what's happening. Special mention goes to the lingering shot on Mary's dying parents, with their faces twisted up in pain.
** The Dreamers in the musical, especially in the various Storm songs.
* PuritySue: Arguably, Lillias Craven in the anime series.
* TheWoobie: The '93 movie gives us a dream sequence of a toddler Mary being abandoned by her mother in the jungle, and crying piteously. It's pretty heartbreaking.
** [[FridgeBrilliance You could consider that scene]] to be {{foreshadowing}} for the end of the movie, [[spoiler:when Colin and his dad run off through the garden and leave Mary alone. That's what finally drives her to tears]].
** The anime series gives us [[spoiler: the CanonForeigner Camilla. She and her mother were hated for being UsefulNotes/{{Roma|ni}}, then her mother dies, later Lillias takes Camilla in as her lady-in-waiting and she falls for her young accountant Hawkins... and loses them both, so she has to leave the Craven's manor while being accused of ''killing'' Lillias since she got up the tree to get ''her'' a gorgeous flower as a birthday gift.]] She is [[BrokenBird epically broken]], and it's a miracle she doesn't commit suicide or something and remains kind to Mary.
