Great, another Terminator film that completely ignores the set universe created by James Cameron.
I absolutley hated T3, it is an insult to anybody that saw Terminator and T2, and anybody that says they liked it are in reality in deep denial. This includes Ah-nold.
There might be SOME hope due to the idiots that made T3 not being involved. However, it is my personal feelings that the series should stop at 3, regardless of how horrid it was. I mean, c'mon, we have Judgment Day for fuck's sake, what else is there to know? The resistance wins, that's stated in the first movie, so there's really no point in stretching it out another three movies.
Although....
One small thing, and this is part of a possible paradox. Reese simply states in the first film that he was born after the war, which at the time was post August 29, 1997. So, if Judgment Day happens in 2004 (in which T3 was set, even though it was released in 2003), it is plausible that given the new surroundings, that Reese may have been killed during Judgment Day. So, if Reese is possibly dead....then who knocks up Sarah?
Of course, the damn writers will probably just throw Reese in anyways
