Terminator 3 is an AMAZING Film...
It has fantastic acting (probably the best of the series), a killer car chase sequence that is (mostly) practical in the stunts and destruction, direction and editing that are tight as all holy hell, Kristanna Loken, and the fact that we actually get to see the beginning of Skynet taking over...
I have absolutely no idea why people gripe about this film. People will find a reason to bitch about anything but this should not be one of them. Head on over to "Salvation" for that slice of crap.
