Re: Terminator Three???
Regardless as to the machine being destroyed that doesn't mean they can't just rebuild a new machine.
Actually there was likely no way to build another time machine. Remember Skynet is a computer defense system.
According to Reese the machine defense grid was smashed. I'm certain the defense grid was essential for the machines to continue the war, because Reese clearly says, "we'd won. Taking out Connor then would make no difference. Skynet
had to wipe out his entire existence."
Watch the interrogation scene again. Really analyze what's being said, because these are all the details about the end of the war that Reese
didn't tell Sarah.
Remember, the terminator went through the time machine first. Sending it through was a last ditch effort for the machines to save themselves. If there were very many machines left, they would have sent more than one terminator to ensure their continued existense, I'm sure. This was why the war should have been decided in 1984.
Anything else doesn't fit perfectly into a completely coherent story, although I did like Terminator 2 and 3.
It's also sort of funny that in the other movies only one terminator/terminatrix antagonist was sent. That really makes no sense if the war was still going and they still had time travel capabilities, and a lot of resources.
In the original, I think Arnold was the last soldier of a loosing war effort...
