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.
Accidental Aesop: Walk with your kids to school to make sure they don't run off or get kidnapped by strangers.
Alas, Poor Scrappy: Lampwick may be a spoiled brat like the rest of the kids that come to Pleasure Island, but his ultimate fate is far beyond what he deserves.
Alternative Character Interpretation: There's a common theory that the Coachman is a Karmic Trickster, a red wearing Evil Counterpart to the Blue Fairy. While she has children learn from their misdeeds and sends them towards redemption, he punishes them for their stupidity and misdeeds by transforming them into donkeys. His nightmare face implies that he might be a supernatural creature, like the Blue Fairy.
The fairy gives Pinocchio a lecture about lying, obviously meant as an Aesop for the audience.
Also the bit "If you don't go to school, you'll become a donkey". Justified in that barely any Italian kids went to school when the book was written.
Don't be an actor. They have no conscience.
Awesome Art: The Animation! There's a reason this is considered one of Walt Disney's better works. Monstro's animation is considered one of, if not the, greatest pieces of animation ever created.
The backgrounds are all masterful works of illustration and layout in it of themselves. Every single one of them is overflowing with detail and texture, from the opening shot of the town square to the knick-knacks on Geppetto's bedside table.
Awesome Music: The whole soundtrack can count, but special mention goes to "When You Wish Upon a Star". That one song was so good, it became Disney's de facto theme song. The song and score both won Oscars.
Complete Monster: The Coachman. Seemingly a kindly old gentleman, he lures a bunch of troublesome boys to an island where they can do whatever they want without adult supervision, and laces their cigars and beer with something that, when they act like jerks, turns them into donkeys he then sells as ordinary animals. From what he says to "Honest" John and Gideon, he has been doing this for years, and the police have never caught him because by the time they arrive, the boys have already become donkeys, leaving no evidence that they were even there. The transformed boys who can still talk are locked up in a pen (it is unclear what becomes of them, though we're probably better off not knowing). Worst of all, he is a Karma Houdininote Although you do kick his ass in the SNES game of the same name..
Designated Villain: Monstro. He's classified as a villain since he deliberately tries to eat Pinocchio and Geppetto after they escape from inside him...but as the book "The Encyclopedia of Disney Characters" puts it, if someone lit a fire inside you, you probably wouldn't be very happy with them either.
Mean Character, Nice Actor: Monstro even guest-starred as a good guy in a Bonkers comic story. According to this comic, he is a well mannered but destructive (due to his size) Toon actor who has not had much work since this film.
Ho Yay: Like it or not, Pinocchio/Lampwick (a.k.a Pinocchwick) is becoming a rather popular ship. Due to their ages, it also counts as Toy Ship.
There are people who notice their interactions in the film and they tend to point out the certain moments that screamed Opposites Attract, hence this pairing. Pinocchio clearly looks up to him and Lampwick seems to be enjoying the attention. Some like how his bad boy quality played off on Pinocchio's innocence. Make of that what you will. Oh, wait...never mind.
It doesn't help, that Lampwick's original name in the novel was said to be 'Romeo'.
Magnum Opus: Considered to be a possible candidate for Disney.
Ms. Fanservice: The Blue Fairy. Believe it or not, this was more of an accident - Walt Disney originally wanted the character to be beautiful, but not like a glamour girl. In the end, the animators were said to have based her on model/actress Jean Harlow and Walt approved the final design.
Narm: It's difficult to take the SNES game seriously because of all the ridiculous sound effects!
Nausea Fuel: When Pinocchio inhales the whole cigar with one breath, and first turns red and then green.
Uncanny Valley: Pinocchio's human form, if you're used to seeing him as a puppet.
Tear Jerker: Pinocchio's apparent death. Also included should be the Adult Fear moment when Geppetto walks desperately through pouring rain in search of Pinocchio when he doesn't come from school. His increasingly desperate cries of "Pinocchio!" ringing out while his puppet-son is unknowingly being carted away just in front of him is pretty agonizing for anyone who's ever been in charge of the welfare of another.
Oddly, enough. you can't even help but feel sorry for Lampwick during the transformation scene. It's not a good view seeing him while he desperately gets down on his knees and begs Pinocchio and asking for Jiminy's help.
And Alexander an innocent little boy like Pinocchio turned into a donkey crying for his mother, the Coachman then roughly throws him into a pen with other talking donkey boys leaving him and the others to an unknown fate where they may never see their families again and may remain donkeys for the rest of their lives.
The Woobie: Geppetto. Seriously, he first desperately looks for his kid, then he get swallowed along Figaro and Cleo in the belly of a whale where he risks to die starving.
Pinocchio. The poor kid's naivety leads him to some really awful situations.
