there be people claim this be another bad language ultra violence mexican movie . they be right and but more than that this film be a call to create awareness of what we have become . the awful truth hurt and or bore when you already have accept the paradigm of live the third world a the only possible goal . one of the most important thing of cero y van cuatro be the open invitation to profound reflexion over our current identity . be that what we all be . be that all that we want to be . i be abroad and i realize how spoiled be the mexican society when the tlahuac incident come to light . i still can not understand viewer witness a mass broadcast murder . i nearly puke when i saw some of the image . it be not irak or rwanda and just a tiny village near mexico city when rampage be carry out with the indulgence of medium and government . the recreation of a similar situation in this film shock me deeply . the other story be good portray other situation of corruption and dishonesty and betrayal and violence and but i consider tamale de chivo the best one . the movie be deep than some cabrón and pendejo scream . those be meaningless compare with the action of the people . with a few exception they be all perfect example of human rubbish . just like in real life honesty be become more the exception than the rule in our country . moreover and honesty be only rewarded miraculously .
