To recall,
the ending it seemd that the aliens that invaded the planet earth died when a sort of virus plugged their computer system. which is magnetically-electronic devide shut the system.
If i will be asked to rate this move, well i can say im not satisfied, if you say war of the worlds in my opinion, there should be at least 3 parties involved and it must be happened outside the planet earth premises, say this is another 'alien invasion" should be
