I feel like TFA and especially TLJ have enough merit to include, and I’ve invested a great deal into each. It ends with the death and figurative rebirth of the main hero, ending on a meta-reflection about people being impacted by the stories.
But, doesn’t it leave the plot unresolved? Not really, since the ST sets up the idea that empires and rebellions will continue to cycle around one another endlessly, anyway. No matter where you end the plot, the themes of TLJ are where they end with meaning.
I can understand this in a way as TLJ actually felt like a conclusion to the trilogy with nothing left for the 3rd movie to go on with, not in any logical sense anyway without taking at least a 5+ year time leap into the future.
