I think the thing that bugs me the most about the Terminator movies is how the machines hate humanity, but they keep designing their stuff to look and function like humans. Stop using our skeletal structure as a base! Why do you build cars that need drivers instead of just building robot cars?!
The Matrix got it right. What do we want? To kill all humans. How do we do it? By abandoning all traces of human design in order to create a systematically superior killing machine. Just flying limbs of death.
Meanwhile Skynet's all "lolz, we made an ahnold again!"
No Skynet! Damn it, you got it right with the T-1000! More of that! ALL OF THAT!
