I'm just amazed we never got to a point where the story became about preserving the causality loop of the original film.
Okay, I still say there should have been no sequels after T2, but if there had to be, then we should have eventually gotten a film set in the Future War where John Connor has to preserve the events of the 1st film by giving Kyle the picture of his mom, sending him back, reprogramming the T-800 to send back, and making sure the events of T1 and T2 take place as they should, with some hitches in the road (maybe Kyle finds out he's John's dad or something, I don't know).
The fact that it is 2019, Terminator sequels are still being made, and they are STILL about time traveling robots and a protector trying to safeguard future Jesus is just asinine.
