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.
YMMV: Chitty Chitty Bang Bang
Adaptation Displacement: The original novel has the family go to France on an impromptu holiday, where they end up breaking up a crime ring.
Ear Worm: "Oh, you, pretty Chitty Bang Bang, Chitty Chitty Bang Bang, we love you..."
"You're my little chu-chi face!"
"Oh, the POSH, POSH traveling life, the traveling life for me!"
"Me ol' bamboo, me ol' bamboo, you better never bother with me ol' bamboo!"
"Toot sweets, toot sweets..."
Seriously, all of the music is ridiculously catchy. Of course, with Robert and Richard Sherman at the helm, this is unavoidable.
Memetic Molester: The Child Catcher is often viewed as one of these by fans of the movie. The lesser-known stage version actually makes him worse, with a Villain Song ("Kiddy-Widdy-Winkies") that many stagings cut for being too suggestive. It probably didn't help that in the original London production in 2002, Richard O'Brien played this role!
Nightmare Fuel: The Child Catcher. An androgynous Snape-like creature dressed in black who dances about singing the joys of candy and ice cream all as a ploy to lure children into his cart and then lock them in giant circus cages.
Special Effects Failure: Chitty just can't fly without being surrounded by blue matte lines — a dead giveaway that the shots were filmed in front of a blue screen. And then there's the fact that Chitty's normally shiny chrome suddenly stop being reflective when the car is flying. That is, except for those shots of just the hood when it's clearly being airlifted over Neuschwanstein Castle.
Unfortunate Implications: At one point, Grandpa Potts mentions fighting "the Fuzzy-Wuzzies", a slur for the Hadendoa people of East Africa, who the British fought against during the colonization of Sudan. May be a case of Deliberate Values Dissonance, since the movie's set in the 1910s.
Vindicated by History: When the film originally came out, it lost money at the box office and was panned by critics. Somewhere along the line, it became a classic.
