To all those who rates it extremely low:
"Oh it's just some rich boys condescending toward the extreme poor" - If trying to raise awareness of extreme poverty is condescension, then all charities are to some extent condescending toward the poor as well. The fact is, helping someone in need DOES NOT EQUAL to condescending. And if you've actually finished the film, you should be able to see how much respect the boys are paying to the people.
"Oh they're not replicating the true poverty situation enough" - Yes, perhaps they didn't replicate 100% of real extreme poverty. Yet, is it that necessary? No! I believe the contrast is already there, sufficient to inspire someone who has never seriously imagined what's it like to live on $1 per day, and to raise awareness on what's happening to the everyday lives of 1.1 billion people.
"Rendered the lives of Guatemalan people as two-dimensional" - Dude it's just a documentary under an hour, what do you expect? Too long and people may lose interest and patience to watch, too short and people complain for lack of depth. You really don't need that much "3D character portrayal" to imagine what's it really going on in Guatemala, do you?
All in all, it's an inspiring film that raised awareness of world's extreme poverty through the lenses of first-world kids. Sure, it's not perfect, but it did inspire many who watched it, and it raised a good amount of charity funding as well, I believe. In short, it's making an impact to the world, unlike many blockbusters which simply provided instant gratifications.
If only everyone donates a tiny bit of their monthly salary to a good charity, the poorest would be much better off. We need more films like this.
