Well, what exactly is the story of TLJ? Already people have been piecing together all that is known.....
- Movie opens with evacuation of D'Qar base and subsequent huge space battle which the FO wins.
- Rose loses her sister in the battle
- Rey and Luke's meeting on Ach-To is explored
- Movie then dwells on Kylo and Snoke's teachings
- Then moves to Leia and that aspect of the Resistance as they scramble together and devise a next move
- Finn wakes up and is given a mission to Canto Bight, this is where Rose becomes an accidental hero and tags along
- There's a whole sequence on Canto Bight, espionage Bond-style under the backdrop of an affluent society
- The mission goes awry as Benicio Del Toro's character back-stabs Finn and Rose
- The FO under Captain Phasma lead an assault, and it's when we probably see all those explosions and Finn and Phasma facing off
From there there's a lot missing, much time goes by. Supposedly the FO also arrives on Ach-To and causes Chewy, Rey and Luke to flee. But ultimately the resistance moves their base to Crait, and Rey makes her way there as now a Jedi, to help her friends, who are in danger, because the FO has intercepted intel, discovered the new base, a huge attack is made there. Perhaps again the FO wins that one, with yet another evacuation, and possibly this is when Kylo ponders pulling the trigger on Leia. Rey is likely captured on Crait, possibly after a battle with Kylo, and taken before Snoke. And then more missing story from here on. With rumors like Luke coming to Rey's rescue, and a face-to-face meeting with Snoke and some huge reveal, and/or Kylo and Rey teaming up, and/or some lightsaber battle between four combatants in the one scene, like Luke, Rey, Snoke, Kylo. Basically the movie perhaps culminates here on Snoke's command vessel, with a cliff-hanger and/or shock reveal.
