The whole Terminator series is one big paradox after another. That's why I gave up on it after the second one. For me, they changed the future. Judgement Day never happend. End of story. But that's just the way I see it.
That and I just couldn't bear to see the series go down the tubes the way that Alien did. Two Terminators were enough for me. Same with Alien. Should have stopped with the second one.
Also, this has gotten way off topic. LOL!
