Adaptation Displacement: You bet your ass that re-releases of Q & A feature Slumdog Millionaire much more prominently than the original title.
Indians Hate Slumdog Millionare: India did not take kindly to this film for having needlessly glamourised negativestereotypes about their country and the city of Mumbai and for portraying India as more impoverished than it actually is. In fact, many Indians were dismayed that Slumdog actually won so many awards, to the point where so much as mentioning the movie can qualify as a Berserk Button to them.
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.
Hype Backlash: It won Best Picture at the Academy Awards. And that is all we shall say on the matter.
Moral Event Horizon: Maman and his gang blinding little boys to become beggars and prostituting underage girls is the most obvious one. He is like the darkest intepretation of The Fagin from Oliver Twist.
Prem Kumar, the game show host crossed it when he tried to cheat and even lied about Jamal and had him tortured for supposedly "cheating". On that matter the police themselves qualify for torturing someone on hours without proof and even if they were right it was Disproportionate Retribution.
Javed Khan as a crime boss was obviously beyond it but onscreen examples are the abuse and scarring of Latika.
For that matter Salim became his willing henchman and helped him prostitute Latika and betrayed his own brother.
Finally what started it all was the cold-blooded murder of their mother and other random civilians by extremists.
Nausea Fuel: How to leave an outhouse over a river with only two exits, a jammed door and... guess it.
If it makes you feel any better, the actor was actually jumping in a substance made of peanut butter and chocolate (basically a liquid Reese's cup).
Poverty Porn: From the left to right, the film has been accused of this.
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?
