This is to say if you liked, as I did, the existential and playful direction Johnson took with the franchise -- in which both characters and audiences were made to interrogate their pre-established opinions on Star Wars lore -- you're bound to be disappointed. If you didn't, well, you might still be at least underwhelmed with the haphazard way in which Abrams chose to bring this all to a close.
If you want to go into The Rise of Skywalker without knowing literally anything about the plot, it'd be best to stop reading here, but these don't really count as spoilers, per se. As indicated by the trailers, Abrams' biggest and boldest move is bringing back Ian McDiarmid's Emperor Palpatine as the principal villain -- in other words, an ex machina villain who had never been mentioned as a relevant player in this timeline. The opening crawl explains that the galaxy has been besieged by mysterious broadcasts coming from the thought-to-be-dead Sith Lord. Palpatine's always been a frustrating puppet-master type whose maniacal brand of evil isn't as compelling as his more fallible counterparts, and it turns out he's serving the same function here.
After Adam Driver's brooding Kylo Ren locates the source of these messages in the opening sequence, the rest of the film finds our good guys trying to get to the same location to save the day. In the case of Daisy Ridley's Jedi-in-training Rey, this particular journey will also mean coming to terms with her own history. (Yes, we find out more about who Rey is, and yes, there will be thousands of takes on this matter.) From the outset, the whole mission immediately registers as inorganic thanks to dialogue that labors to dump all the info necessary to understanding just what the hell is going on. The natural chemistry between Ridley, John Boyega, and Oscar Isaac -- as Rey, Finn, and Poe -- do wonders to keep matters entertaining, for the most part, even when the mechanics around what their characters are doing border on nonsensical.
