I rather enjoyed "The Rise of Skywalker." I'm a lifelong Star Wars lover, and this one, overall, did not disappoint. Certainly not perfect, but pretty darn good in my opinion. I honestly expected Disney to disappoint much more than they have, but they've done a pretty good job. Overall, the Disney movies are much better than Episodes I, II, and III. "The Force Awakens" was quite poor, and I prepared for the worst after that, but I think they improved greatly with "The Last Jedi" and "The Rise of Skywalker." That said, they hit a freaking monster homerun with "Rogue One." As blasphemous as it may sound, Rogue One is right up there with the originals in my opinion.
Haven't seen Mandalorian. For some reason, it seems like a Star Wars series will trivialize the whole thing for me. I like the anticipation of waiting a year or two or three for a big blowout movie experience. Absence makes the heart grow fonder, or something like that. They are just about the only movies I'll actually drag my but to the big town to go see, so it's a pretty big deal when a new Star Wars comes out. Plus, I'm just not going sign up and spend any amount of money on yet another subscription streaming service.
