A Canadian photographer shows you the dehumanization behind the Chinese economic miracle, like any industrialization process (remember Germinal by Zola in the 19th century?),the absurdity of waste yet its beauty, the merry-go-round of globalization. The movie is sometimes a little slow but maybe you want it to finish faster so that you can go back to your way of consumming as usual. It will be hard to discard your cellphone without a thought, or turn on your engine to go and buy bread, the images will hover above your shoulder and haunt you like a gardian angel warning you "do not do it!".Two of the most amazing scenes besides the opening one are: the destruction by its own dwellers of the houses that will be flooded by the building of the Big Dam and the dismantling of the old oil tankers in Bnagladesh. I recommend this movie as a lesson of happy sobriety.
