Saw First Blood for the first time ever. I knew what it was about; what surprised me is that almost all the characters had that single-mindedness normally reserved for the Evil Guy's nameless henchmen.
OK, the protagonist has obvious mental problems. OK, the sheriff liked to be mean to helpless drifters (that kind of people usually tend to back off when the victim turns out to be not so helpless, but let's assume this one was dedicated to being mean). OK, some cops probably hit the uncooperative detainees with only like-minded cops for witnesses.
But a police officer trying to shoot and kill a fugitive? In the presence of a disapproving colleague? And then threatening to kill that same colleague for trying to stop him? While the colleague is piloting the helicopter from which the shooter is sticking out with no safety belt, and only his butt inside?
