Great, just GREAT! This is one of the FEW Sci-Fi movies I have watched over and over and over and (you get the point (others like it are CONTACT))... Although the plot is highly unrealistic (at least I think so), it makes you think "Do we entrust computers with too much? Should we make them so "smart" that they can do most stuff for us?" This is one of the movies where I am impressed with Arnold... He plays his role almost PERFECT (hardly any lines, just a cold, rutheless killing-machine). And Linda plays her role exelently too.
The movies has a lot of everything needed for a good action flick: lots of action, lots of explosions and lots of chasing/stalking (and a tad of love), but it manages to balance in the grey area between too much and too little, making this a true masterpiece.
The story of a world overrun by 'borgs, using the few remaining "fleshies" as slaves can easily get boring, but this movie keeps the excitement up from beginning 'till end... (Not too gory to watch with your girlfriend, but not too lovey-gooey to watch with the guys (have you seen 5-6 guys gathering for a night of a few beers, some pizza and Titanic?))
There aren't many movies like this one...
