I don't know! I have seen it and it's a good film, not a masterpiece (imho) but worth to have a look, another one at the same level is one called BARRIO, all about teenagers and children living in suburbias and the outskirts of Madrid or a big city and the dreams they have and the reality of their daily lives.
I like them because they don't make any concessions to the public and are very honest. I hope you can see it sometime! Let us know!
