Can someone explain me the timeline , cause it became a mess after T3 , mind that i didn't watch DF yet but i read that John dies in this which happens just a few years(5-10?) after the events of T2 , so how the hell is John alive in T3?? which happens years after this movie let alone the fact that he sent Kyle Reese from the far future in T1, so which movies are canon ?
According to Cameron, only T1, T2, and now DF are cannon so this is the one true sequel to the first two.
Personally, I say BS. There is the timeline of T1 where John grows up and becomes the leader of the resistance - IMO, that will never change. I consider T1 to be a stand alone story and T2 exists in another timeline. Despite all of the debate about it, Cameron has said, and I agree, that Kyle was always John's father which means the story never changes and loops over and over again . I personally like the concept of T3 being the sequel to T2 rather than DF, where judgement day is just delayed and will always happen and John continues down the path we know, but that exists in the timeline of T2, not T1.
