TLJ has none of that mystery because it picks up literally where the previous installment leaves off, and that’s J.J.'s fault because he just had to have his dramatic ending and couldn’t tell a complete story
I really, really disagree with that and I don’t understand why its become such a common argument for TLJ.
Rian wasn’t forced into anything by JJ,
Rian was definitely forced to do certain things based on the way things had played out in TFA,
I guess it might have been interesting to do a time Jump. But so much of what was alluded to the end of TFA would have had to have been just ignored that I can’t imagine people would have been happy.
