Charlie/Parson Theory

I'd disagree with that; Terminator is much more of a You Can't Fight Fate series.

It's a bit all over the place.

Terminator 1 leans towards the idea that the future is unavoidable.

Terminator 2 does an about-face, with the 'No Fate, but what we make' message.

Terminator 3 either goes back to the future-is-unavoidable idea, or makes the point that Skynet can mess around with the timeline just as much as Sarah and John Connor can - interesting to note that the Skynet that sent the T-X is a different Skynet to the Skynet that sent the T-800 and the T-1000.

The trailers for Terminator 4 seem to hint that time has been so messed around, John hasn't got a clue what's going to happen beyond 'robot army'.
