Rambo combines an unapologetic return to the grand action-movie tradition of blowing shit up (one explosion is so big, it leaves behind its own miniature mushroom cloud) with a Saw-era interest in close-ups of human viscera. The problem is that the moral meaning of the gore keeps changing. The airborne organs of a helpless Karen villager are supposed to make us scream, "Rambo, right this injustice!" while the splattered guts of a Burmese army officer are meant to evoke a reaction along the lines of, "Aw yeah."
