I just came back from watching Terminator 3: Rise of the Machines.
It was good. Very good. As good as the Last two. I will definitely go see it again.
*** WARNING: SPOILERS ***
So... Judgment Day was not averted because of the events of T2. It was only delayed. Now, T-X has been sent back in time to kill John Conner and his future lieutenants, and another T-800 sent back to protect him. T-X is beautiful, very beautiful, I like her!

She is also a very dangerous and efficient killing machine, more advanced than the T-1000, with new abilities. Lots of destruction, explosions, and wrecked cars and buildings, as T-X and T-800 battle each other. The scary thing is that the story of Skynet taking over computers, AI- controlled military drones, and the nuclear missiles sounds disturbingly plausible. The surprise ending was rather dark and not very happy... I wonder if they will make a T4?
