I do not understand

Rating: Null/10 (7 October 2005)

why after one machine was killed by Ray, all the other machines die one by one? I did not quite follow there, maybe because my English was poor. Can someone tell me more about it? I thought the director will present a intense-fighting scene in which human beings defeat those machines. But it seems to me that is not the the the director's interest. He focused more on how people react to the disaster or invasion, and how disaster make people know and understand each other.
