So I've never seen the Terminator movies. I've seen bits and pieces here and there, but never an entire movie. I've picked up enough to know that the future is destroyed and run by machines, but that a band of humans, led by John Connor, rise up against them. To stop this from happening, the machines send (a) terminator(s) back in time. Excellent.
I can't even recall how many times I've seen parts of The Terminator. Enough times that I actually figured I had seen the whole movie, just not in any linear fashion. Recently, USA has started showing T2 (repeatedly, it seems), and I've seen a few scenes. This past weekend, though, I decided that it was too confusing and that I was just going to watch the entire series - from beginning to end, with the TV show thrown in for good measure. So to Netflix I turned.
As I started watching Terminator "the original" I realized that I hadn't actually seen it before. Then, much to my surprise, I see that Terminator-Arnold is actually the bad guy.
Apparently, I've been watching movies 2 and 3 all this time and had never seen even a bit of 1. As such, I thought that Arnie was always a protector terminator. Whoops.
