Sure there’s a big gap, but all events are trending in the direction of the status quo at the beginning of the movie.
It’s rather like going from Attack of the Clones straight into A New Hope. The Republic was becoming an Empire, its armies were being made, Anakin was practically evil by this point, the Jedi were on their way out, etc. Sure, there are questions about how all these things happened, but it’s more interesting to speculate than to fill in all this history with imagination-destroying answers.
All this to say, I would have watched another season. All I’m getting at is maybe there’s a silver lining.
