The movie is cool, with the highly-advance weapons and fighting actions, adrenaline pumping scenes.

Though, it is not really an everyone's-favourite movie. For example, one of my friend, a girl, complained that (well, as she interpret) she was watching 'flash-scene' which nearly got her blind. What she meant is, some scenes of the movie were made so that all you can see through naked eyes are the jets/submarines flying here and there in the speed of light, which is kinda annoying when there's too much.

I still like the movie. Of course its not realistic, but who knows what will become of our world when nanotechnology really grow with such rapid speed right? Nanotech is one thing that cannot be looked down!
