Rocky was never a meant as a trilogy of films. Aliens is not meant to be completed in 3 acts. Star Wars is meant to be a beginning, middle and an end. Look, I'm not going to pretend I know everything, but I'm enough of a creative person having worked with enough people in the creative industry both professionally and personally to know why JJ was doomed to fail with this film. Saying there were enough point lefts over doesn't actually prove anything, if anything, it actually proves the problems JJ faced because there was nothing obvious to latch on to to build a conclusion. Nothing of those threads were the basis for something that could have been crafted into a compelling finale. That's got nothing to do with JJ being a hack like some have unfairly said, it's got nothing to do with lack of time, it's that he had little to work with. You could have given the man 5 years worth of time and he still wouldn't have been able to craft something on the back of TLJ because that film for all intense and purposes broke the structure that was originally laid out. Once you do that, there's nowhere left for you to go other than try and scrape together whatever you can. If you think you can come up with a compelling third story that somehow manages to make sense of both TFA and TLJ and bring an end that is satisfying, I'd be genuinely interested to see what you'd come up with, because for 2 years I've been racking my brain trying to think of a logical path to start film 3 with and came up with nothing. And it would appear JJ had the same issue.
