@Linkat,
You're right, Linkat. A lot of Indians do feel that it's too negative a picture of India.
A lot of my friends said so...and they also said (in the same breath) that it's too cliched...
There have been several movies about India and the poverty here but Indians made no noise about that. I think that reaction could be coming because Indians probably see the movie as too simplistic a portrayal of the hard life in the slums of india.
I liked it a lot (mostly because I had already read the book and knew what kind of movie it would be...). I most liked it for the imagery, music, and the story format....I thought it was very clever to mix up painful events with fairy-tale-like good luck and hope. Yes, and as Vinsan because it kind of explains itself....
But I also somehow felt the movie went at breakneck speed - I somehow wished it was a bit longer!
I read the book too (Q&A). The book and the movie are different (the book is even more fantastic, fairy-tale-like, even as it narrates painful events) and I liked both.
