I think The Terminator, Terminator 2 and Terminator 3 are all excellent films. I don't understand why T3 gets slagged off so much. It's one of the few trilogies where the third film is also a classic IMO. It was quite different to T2, especially in Arnie's portrayal of the Terminator, but then T2 was quite different to T1 in the same way. The third one had some brilliant stuff in it - I loved the parody of the "I need your clothes" scene from T2, and the crane chase is one of the all time great chase sequences in movie history. (I read that they actually considered flipping the real crane over in the street but opted for cgi on health & safety grounRAB). And the shock moment when O'Connor asks when Judgment day will begin and Arnie tells him it starts in 3 hours time.
And all the sexual reversal stuff with the Terminatrix penetrating male sex symbols (cars, etc.)
Excellent stuff!
