So you didn’t notice the recurring the theme of being able to rely on your friends just like in ROTJ? The attempt by Kylo Ren to turn Rey to the dark side, just like Vader did in ROTJ? A (bunch of) new planet killing weapon that threaten to solidify Palpatine’s power in the galaxy? The ragtag bunch of rebels on a do or die mission to destroy said weapons? The rebels can’t destroy these weapons until a small strike force take out a vital piece of infrastructure or the whole assault would be in vain? Palpatine’s disciple ultimately switching sides and sacrificing himself to save the protagonist? The protagonist ultimately facing their fear and refusing to do Palpatine’s bidding by not giving in to their fear and hatred? All of which was lifted straight out of Return of the Jedi.
You didn’t notice any of these things Griff? Are you sure you went to see Star Wars?
