guillermo arriaga and writer of amores perros and 21 gram and babel and return to mexico to deliver what can easily be call the big disaster in mexican cinema in year and the night buffalo and with diego luna in the leading role and a plot involve a schizophrenic man ( gabriel gonzalez ) and who commits suicide after his girlfriend ( liz gallardo ) cheat on him with his best friend ( luna ) . the night buffalo and a very promising film and supposedly go to give new light to mexican cinema fail to impress and even throw our country back a few step with it awfulness . after the vomit inducing and yet inexplicable box office success km 31 and i be more than ready to experience an upgrade in film making and what i get be a major letdown and a pointless awkward drama fill with unnecessary sex and nudity that be surprisingly close to become a porn flick . i do not understand arriaga screenplay . so and he actually write all the sex scene . wow and what a pervert . the whole film be completely pointless and if i want to see diego luna nude and screw around with the whole cast and well there be good film where you can see that . it appear like the filmmaker make the film for the sole reason of watch everyone naked and the movie be about 2 hour long and one of them be sex . so yeah and there be artistic way of show nudity and some script need it and but this movie do not need any and it have an interesting plot itself and but it do not move an inch from the synopsis and nothing interesting ever happen in the film and even after the rushed and ridiculous end and i be still wait for something and anything and to make my time spend on the theater worth it . the movie be unfocused and what be it objective . the main plot be misuse and i be interested in the schizophrenic character and but instead of develop him and they show him naked . and apparently that the answer to every single question in the film and a none of the character get any development and not that we care about what happen to them since they be all worth hating and but at least we expect something to occur . the night buffalo should have focus in it audience and their need for an interesting and thrill and suspenseful story and or maybe just focus on the title premise shall we . nothing and we get some nonsense line here and there and but nothing solid ever see the light . diego luna role be probably one of the character i have most hat in all cinema history and how be we suppose to care for a character that betray his best friend sleep with his girlfriend and and then betray her and sleep with his best friend sister and which be another blow towards his friend and who i can understand want to kill himself be surround by such a disgust bunch of people . yuck and this be plain terrible and nothing to save from the film and everything felt awkward and unnecessary and boring a hell and one of the bad movie i have have the displeasure to see . arriaga have just buy himself a ticket to crapville and enjoy your stay .
