Wow, fans of Salvation are a VERY small minority. Sure it had its flaws, but there was some interesting stuff there that expanded the terminator universe, and a lot of nods to T1 and T2 if you pay attention. I liked it so, so much more than T3, which Ahnold couldn't even save. T3 just plain sucked more than words could ever express.
Of course, T2 is the greatest there will ever be.
We need to stick together!
Yes, there are a bunch of things that relate back to the first two. I think it fit in very nicely as a prequel. I gave us little things like where Kyle learn't to tie a gun to his arm,"Come with me if you want to live", Connors scar in the future in T2, and the list goes on. I can't think of another prequel that paid so much attention to the films that it was leading up to. I'm not sure what so many people disliked about it. I've heard many people call it the worse of the franchise - Those that hated it, what was so bad? Even as just a movie, it was interesting, had a good pace, the filming wasn't done in that shakey free-hand style that became oh-so popular. I think the effects will stand the test of time. I even think the casting was done pretty well. Don't get me wrong, it wasn't perfect, but I was satisfied with it.
T3 on the other hand... My beef with it is that is really takes the first two and says those were for nothing. It spits in the face of fans. T2 has a strong theme of (one of many) being able to make you own path (there is not fate but what we make). The T-800 (in the directors cut) is given that opportunity when John resents his switch to 'learning'. He gives the machine a future (or, at least tries). John and Sarah change the future but destroying Cyberdine. Even Miles sacrifices everything he worked so hard for to break free of that future. The whole movie is a struggle to change your fate, be it a mindless robot, the leader of the future resistance, being locked up in an institution, or building a pilot that never shows up hung-over. T3 says, 'Just kidding, it's gonna happen, no matter what you do {so we can sell more movies that make a lot of money}'. It left me thinking, 'why did we fight so hard? What was it all for?'
Finally, let's talk about the new Terminator. The girl. Whatever model it was (T-X, gimme a break. Put less effort into that.) She doesn't fit. The T-800 is a tank. Cameron, for the second film, felt that the new Terminator has to be something faster, meaner and leaner: a sports car. Excellent. But the girl? What's that supposed to be? A Vespa?
As for SCC, I liked it. I think like most shows that came from a movie, you have to treat it as a separate universe. In that light, it was more Terminatory goodness.
