The end is basically "welp, we failed" and everything goes boom. Skynet win. Then Connor start talking to the radio from the bunker and sort of become the de facto leader of the survivors.Oh you mean of the whole movie? No idea, did completely erase it from my timeline.
I liked it, it was no "happy ending", and I like the whole cycle thing/by trying to escape fate you provoke it. So there we go^^
