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.
Angst? What Angst?: Matilda is The Unfavourite, stuck in a grade beneath her intellect, and faced with a headmistress from Hell. In spite of this, she's a cheerful kid who is genuinely nice to pretty much everyone. Pretty much one of the subtext points of the book. Matilda was in a crappy situation, more than one actually, but remained a good person throughout. She's more than a survivor, she's come through her ordeals wiser and still human. Even when she discovers her telekinetic powers, they're used only to punish the Big Bad for good and not mistreat others as a bully. Matilda could have caused a nightmare like Carrie with those powers, and yet luckily she didn't harm anyone.
Hints are dropped that the Trunchbull had her own tough childhood ("Glad I never was one [a child]" and "Not for long anyway; I grew up very quickly", for example). She also clearly values physical and mental strength and resilience, as evidenced by her Olympic career, constant shows of power, and some of her dialogue. Furthermore, some of her dialogue implies that what she hates most about children and childhood is childlike innocence and naiveté.
It is quite possible that the Trunchbull sees herself as a survivor of a harsh world, and wishes to toughen up the children to do the same. It is even possible that she wants to save them an even harsherBreak the Cutie, but severely overestimates the harshness of the outside world, and has become He Who Fights Monsters, delivering a far more harsh Break the Cutie than anything else is likely to.
Trunchbull: I broke your arm once, I can do it again, Jenny.
Family-Unfriendly Aesop: There really are stupid and terrible people in the world who hate you for no reason, and sometimes get away with horrible things. The good news is that if you're creative you can get your revenge on them, and in fact you should, as long as you remain a good person. Beautifully stated in the musical version with the song Naughty.
Some parents also see a Family-Unfriendly Aesop in Matilda's adoption by Miss Honey. As in, Matilda allowed the first nice person she saw to adopt her. When you consider the actions of some teachers these days, some parents find the Aesop unfriendly just because the nice adult happened to be a teacher.
Some Anvils Need to Be Dropped: Just because they are your family doesn't mean you have to be put up with being mistreated by them. A valuable lesson for kids and adults.
Values Dissonance: Agatha Trunchbull's abuse of children, even by both by 1988 note book's release and 1996 note film's release standards, wouldn't be acceptable at all and social services would've been on her case on but none of the children how a way to report since their parents wouldn't believe them... at the time. Nowadays, parents would get suspicious and many children would have a a smart-phone to record their proof. In fact, with anti-bullying laws and social media, Trunchbull would've been caught on the spot and the Wormwood family would have to deal with Social Services.
On the other hand, the Trunchbull might have been savvy enough to confiscate any and all such devices right from the beginning. She's not that stupid.
What an Idiot: Mr. Wormwood's approach to selling cars. He intentionally rigs the cars to break down after a few miles thinking that his customers will return to the dealership that sold them the crappy cars in the first place to throw their money away on one crappy car after another. It never occurs to him that his dealership might get a negative reputation and eventually receive no business at all because everyone knows that the cars are little more than spray-painted junk.
When the Trunchbull is talking to Harry on the phone she says something along the lines "Yeah, I know the buyer have to protect themselves, but you´re a fraud!".
The Woobie: Miss Honey, Matilda. In the book version, the school cook as well. She's not gross like the movie version. Here, she's just a frail, old woman who disapproves of the abuse about to happen, but clearly has no choice but to play her role.
Fridge Horror: In the book, it is mentioned in passing that Matilda read Tess of the D'Ubervilles, which deals with the titular character having been raped. It's mentioned to highlight Matilda's status as a Child Prodigy, but still, it's more than a bit horrifying to think about a five year old reading something of that subject matter.
We're meant to see him as an unsympathetic Jerkass since he's downright nasty to his sister and participates in his parents' dirty dealings. But, before we judge the poor kid, we ought to consider that Harry and Zinnia have probably conditioned their son to be this way, meaning there's Fridge Brilliance: Michael has figured out that by conforming to his parents' lifestyle rather than rejecting it like Matilda does, he won't be picked on. Matilda is exceptionally brave and intelligent; she can stand on her own and doesn't need her parents' approval to be fulfilled. Michael is neither brave nor intelligent enough to resist the pressure to become a mean, lazy, TV-watching Wormwood.
Draco in Leather Pants: The Trunchbull in the movie, mainly because Pam Ferris' performance makes her entertaining despite all the atrocities she commits.
Fridge Brilliance: In the movie, the Wormwoods go to Guam to get away from the FBI. Guam is a territory of the U.S. and the FBI would certainly be able to find them there. But, since they are incredibly stupid, TV-watching slobs, they probably didn't think of that point for one second.
Bit of a Meta example, the song "Little Bitty Pretty One" by Thurston Harris plays when Matilda learns how to control her powers. While on the surface it's a whimsical moment. On the meta level, it's the same song used when Christine goes after her first victim. And since stuff gets real later on after that montage.....
The scene where Matilda has snuck into the Trunchbull's house, hiding under the table as the Trunchbull's shadow gets closer... closer...
The scene where Matilda "haunts" the Trunchbull's house is pretty creepy too. Think of it from the Trunchbull's point of view: the clock keeps striking each hour, her portrait is shoved into the fireplace by an unseen force and is replaced by the portrait of someone she presumably murdered. Scary shit.
What Do You Mean, It's for Kids?: The film has a bunch of kids getting hammer-tossed out of windows, first-graders getting packed into a closet with rusty nails and adults downright insulting childrens' intelligence and calling them hurtful names. Then again this is Roald Dahl we're talking about. On the upside, the abuse isn't that severe and the protagonist does win in the end. On top of that, it's a family film, so the violence is mainly for the adults, no matter how cruel it may seem.
Award Snub: When the 2013 Tony's came around the four little girls playing Matilda: Oona, Bailey, Milly and Sophia were snubbed from the Best Actress in a Musical award unlike their West End counterparts who were nominated for the Olivier and won. The excuse was that the judges might not have had a chance to see all four girls which is fine until you discover, the three boys who played Billy Elliot were eligible (and won). Instead they get Tony Honors for Excellence in Theatreyay
It got even worse after the Tony Awards, fans were NOT happy that Matilda didn't win Best Musical, it lost out to Kinky Boots.
Ear Worm: So many from the musical. "Naughty", "When I Grow Up" and "Revolting Children" in particular.
Ensemble Dark Horse: Subverted, whilst all Matilda's are reasonably praised, West End!Matilda's Sophia and Eleanor are the most popular seemingly.
Fandom Berserk Button: Just remember, what ever it says in the Playbill, it's the Escapologist. NOT the Escape Artist.
Genki Girl: Not in-universe but Broadway!Matilda Oona is definitely this and West End!Matilda Eleanor is to a lesser extent.
Out of Focus: West End!Matilda Sophia is always speaks less in interviews, compared to say Cleo. This interview highlights it and she always looks moody. In reality she is a massive sweetheart and gave up her Matilda contract because she missed her normal life, looking forward to going back to dancing and violin lessons and almost turned down the role. Not to mention thanking her brother and sister on her Olivier speech. Aww.
