It looks good, but I am a tad worried that as with The Force Awakens vs A New Hope, this will be following too similar a narrative of a past movie, this time the Empire Strikes Back.
We had a similar young adult discovers they have the force and blows up a huge planet killing weapon in The Force Awakens. This one strongly suggest we have Luke playing Yoda training new Jedi and being worried about her being too strong and being seduced by the dark side. And then said temptation happens. The Force Awakens gets away with the familiar plot because it was a celebration of the old movies and we all were happy to see the old characters and a movie that did not suck. But if a second one too strongly follows the TESB plot or is a mash up of TESB and ROTJ, that could be bad...
