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.
Adaptation Displacement: You bet your ass that re-releases of Q & A feature Slumdog Millionaire much more prominently than the original title.
Americans Hate Tingle: And Indians hate Slumdog Millionaire the same way, for having needlessly glamourised negative stereotypes about their country, or even a prominent city. In fact, many Indians were dismayed that Slumdog actually won so many awards.
This doesn't come out of nowhere quite as much if you're familiar with Bollywood films, which use "everybody dances" endings often. If you aren't, it will probably just invoke a Flat "What.".
It also could be seen as a reference to the earlier scene when they are kids. Before Jamal is about to sing for Maman, he asks Latika to dance with him and performs a silly dance for her. Some of the dance moves he does are repeated during the Jai Ho dance and the kid actors reappear during the dance, highlighting how the two are finally together.
Cliché Storm: For Bollywood viewers. Directly caused its poor reception in India.
Complete Monster: Slum boss Maman is charming, friendly and cheerful to orphans he meets, offering the young Jamal and Salim ice cold coca colas and offering them a place to stay. It is revealed Maman takes in orphans to use as a begging ring for him, and the kids are just free labor. Even worse, cripples earn more money, so when children display good singing talent, Maman has them blinded with acid to increase the revenue. When Salim and Jamal escape, Maman captures their friend Latika and several years later gives her the name 'Cherry' while intending to use her as a child prostitute. The only reason he hasn't done so already is as a virgin, she's worth a great deal of money. When he finds the young Salim and Jamal, he immediately plans to kill them, declaring "Maman never forgets."
"Funny Aneurysm" Moment: Almost to the day when the film is being released worldwide — the platforms of the CST, where much of the film (e.g. the "Jai Ho" dance sequence) takes place, is the scene of a particularly bloody terrorist attack.
Harsher in Hindsight: Life Imitates Art to a small extent for the slum-dwelling child stars. One of their houses (still a shack, their limited compensation being tied up in a trust fund) was bulldozed by the government, and another faced allegations that their family tried to sell them for adoption to a wealthy couple.
Also, Anil Kapoor's pronounciation of the word, "Millionaire."
Nausea Fuel: How to leave an outhouse over a river with only two exits, a jammed door and... guess it.
Strangled by the Red String: Jamal is in love with Latika and literally risks his life to find her because... they were friends as kids? Granted, they went through some very rough stuff together, but it's entirely possible for two kids to go through a bad time and not fall in love. The presence of the trope is only confirmed by the movie's explanation for their ending up together: "It is written". They're together because they HAVE TO BE, OK?
