I liked it. It shows some of the realities of life that about 35% to 50% of the world faces everyday. It had a great story too, perhaps about 3 different stories going on at once, don't want to say too much so I don't spoil it for anyone wanting to see it.
I went into the movie thinking it's one of those overhyped movies, I've liked very few oscar movies.
It was a juxtaposition of modern cruel realities with old time values and innocent romance, with adorable children from the slums who can really act, and an unlikely hero that you end up rooting for -- with really hip editing, adventure and awesome music!
