Why would anyone make this movie?

Rating: Null/10 (13 November 2007)

Maybe I'm admitting to old fogey-hood, but, to me, this movie is bad for society, though it's effective, disturbing cinema. I can see two powerful fallouts from it: 1) people with a violence problem have found a new hero. The movie makes it seem realistic that this Terminator-like avenger could actually be that continually successfully lethal and impregnable. Someone will channel that guy. 2) Is anyone going to stop to help a stranger after seeing this? Is anyone actually going to want to interact in any way with a stranger??? These points, though heartfelt, are somewhat ironic. The movie could also be looked at as a statement ABOUT our society which glamorizes violence. Yes, it was effective, but I worry about its impact
