I would agree with the author's (inferred) condemnation of the movie for its religious malevolence, if it was a forced, untrue story.
Truth is more important than hurt feelings.
We all know India went through a partition of epic proportions and that it was not Gandhi's plan to gain independence so divisively. We know that thugs can appear from both sides. So in a religiously blind world, we could make the heroes of the movie Hindi, subject to Moslem violence or vice versa. No matter. The fact is, it could have been this way.
What is the point of pointing out that Hindus are offended? If this is the raison d'être of the condemnation, I can't see the purpose. Better to point to other, easily rentable movies wherein the protagonists, and the whole story, are of Hindi culture and religious roots. I suggest Salaam Bombay, for one. This movie is about a boy, sold to a traveling circus, as I remember and left behind by accident. How he survives in what is now called Mumbai is incredible--much more gritty and realistic than Slumdog (which I viewed as a charming and romantic mythology.)
Fiction is not always based upon documentable accuracy. The questions themselves were too simple for the show. Any college-educated American could have gotten them all.
A good example of excoriating Hindu racism, sexism, and blatant cruelty can be found in the movie The Bandit Queen. Let them feel that one, which is a true story, BTW.
City of Hope is another--hope I have the name correct--it stars John Swayze, star of Dirty Dancing, as a young doctor in India. Then one might go way back and see the 1960s Italian documentary Mondo Cane or "Dog's World." That one is probably the first ever filmed of the mutilation of captive children for income as beggars.
Another letter here below mentioned the corruptive influence of money as a theme. I agree. And we could also begin to seriously investigate the worldwide abuse of children on every continent. Much of it is about money. Examples in film abound--Rabbit Proof Fence jumps to mind. Dickensian cruelties are commonplace. The fear in growing up homeless and unloved must be traumatizing--it's amazing we do so little to prevent it. These slums are the incubation places of terror and gangsterism.
See the Brazilian movie, City of God. See Grand Central. None of these have anything to do with religious prejudice...only children.
So, I'm sorry, Ms. Author, about someone's hurt feelings, I have to ask you, so what? What about the kids who don't win the lottery?
