Oh, and the Sarah Connor Chronicles takes up after the last Terminator movie. She and her now-teenage son have been living on the run. They think the future has been all fixed - until another borg (or whatever they call 'em)shows up in his high school classroom one day. Luckily, there's also a good female borg sent from the future to protect him - played by the girl from Serenity.
The rest is pretty much extended chase scenes, but it's the writing and dialogue that makes it good. (The TV mom does NOT have the same buff arms as the Linda Hamilton, though!).
