Everyone is born, but not everyone is born the same. Some will grow to be butchers, or bakers, or candlestick makers. Some will only be really good at making Jell-O salad. One way or another, though, every human being is unique, for better or for worse.
Some scenes are not reasonable. I don't see why corps can fire with the crowds around in the downtown area. Also I don't see why the general can still hold his position after the bio-hulk soldier lost control killing and destroying the whole city. Good story-telling though.
