“when we started and there wasn’t a finished script, it all of a sudden became clear that it [Terminator: Dark Fate] might not be a good movie.”
Linda Hamilton
After reading this I thought how I’d fix the movie and I think it should be this, after Carl kills John that Sarah should be the resistance leader but still in the canon time line when Skynet became self aware, it would make sense to see her old in the future fighting the machines and could be a twist that she already met her husband to send him in the past to save her so John could be born to be the leader instead (but we already know she is but it’s her hope that he will by stopping skynet from sending Terminators back to the past) and it would be emotional at the end when they defeat skynet but what she didn’t know, Carl was already sent but it be a end credit video
Ya I know I probably spoiled it but it’s just a concept @James-Cameron could do something with it
