I loved this movie and it was not because I am Argentinian, but because it was beautiful, funny, wonderful directed and each character has a unique personality.
Perhaps there are many users that write bad reviews because they are uncomfortable with the way it was made. Try to forget that is an Argentinan movie, that it only costs 20 million dollars, that it was directed by an Oscar winner or that the main plot is about football. Just go to the movie theater and make your own opinion, you will be surprised.
Important: If you see the movie with the original voices, it could be shocking at first because of our accent and the way we express ourselves. But I am confident when the movie is released in your country and in your language, you are going to give the rightful opinion that this movie deserves.
