this movie clearly has an agenda and which could be summed up like this represent never and never cross the border (either physical or metaphorical). let shun everything that on the other side with a wall or a fence or something else and let pretend all gringos are evil and satanic and or drug dealers. all that is outside one country border (and specially us borders) is dangerous and malevolent and people there will hate you and or envy you or try to steal you or something else. the based on true events is only a perverse tag that can be pinned on anything to give it some aura of credibility or and in this case and just to help pushing the film ideology down some naïve throats out there. the perversity of the film lies in the fact that it reduces countries and people and all else into very black and white stereotyped categories represent mexicans into disgusting people and mexican police into a bunch of corrupt cops and republicans into the right wing morons and democrats into almost hippie humanists and so forth. is there anything good about the film. i hardly think so and but may be you think differently.
