The original and prequel trilogies are worthwhile viewing. The sequel trilogy, however, presents a different case. While George Lucas provided story treatments during the 2012 sale, these were ultimately discarded. The sequels also marked the end of the Expanded Universe, removed from canon to allow creative freedom for filmmakers. Given that the stories deviate significantly from Lucas’s original vision, is there really a compelling reason to watch them?
I would say:
The Force Awakens: Not bad, basically a knock-off of A New Hope story-wise but it feels like Star Wars and is pretty harmless fun.
Rogue One: Probably the best of the Disney Star Wars movies IMO, although it does have a couple of dodgy “bringing back an old actor as CGI” scenes.
The Last Jedi: Lots of people hate this one, I’m slightly more forgiving. I think it tried to do something a bit weird and different, and it didn’t really work. But I do appreciate the effort of not just playing it safe.
Solo: A Star Wars Story: Another one that seems to get a lot of heat, but I thought it was pretty inoffensive. Although my brain did kind of delete most of it as soon as it was over lol.
The Rise of Skywalker: Legitimately one of the worst movies I have ever seen. I can’t even call it a bad movie, because it’s essentially just a random series of Star Wars-themed sounds and images that batter you for what feels to be about a year and a half before it mercifully ends, taking with it any good will towards the franchise you might have had left.
