Everyone and his dog gets it that Arnold needs to play a human resistance fighter in this one. I hope the producers get that as well.
"Going back to the roots" is a bad thing in this case. I don't want to see yet another "Terminator travels back in time and needs to be stopped". I want to see the full scale future war that we've seen hinted at in T1 and T2, and how they defeat Skynet, and start the time traveling loop.
