I probably wouldn't have gone to see it if I didn't have grandchildren who are very interested in it. I'm interested, too, but not all that interested; I would have waited till I could see it on Netflix or Amazon.

I haven't read many reviews, but I have the impression that most reaction, at least from people who care enough to review it or discuss it on the internet, has been on the negative side. And if you read the commentary of a true fan, you'll find all sorts of details and disputes about whether this or that aspect of it was good or bad. There seems to be a lot of discussion about whether this last trilogy is coherent, as the second film in it was directed by a different person from the one who did the first and last. And there's a lot of discussion about whether this trilogy completes or defaces the original.

(If you are not familiar with Star Wars: the main storyline is covered in three trilogies, episodes 1 through 9, which tell a story in chronological order. Discussion of these is sometimes confusing because that is not the order in which they were released, which was in sets of three: 4, 5, 6; 1, 2, 3; 7, 8, 9. Complicating the discussion are a few movies and other "product" which are not directly part of that main story.) 

I don't really care very much about all that. The Star Wars movies are not great art. I don't think they will be regarded as such a hundred years from now. And the critics who complained about all the plot devices that have been recycled from the first trilogy are right. This is at least the third time that the resolution has hinged on a desperate mission (apart from the furnishings, a reprise of World War II air combat dramas) to stop the Most Evilest People Ever from using the Most Ultimatest Weapon Ever to rule the galaxy. (If I had been one of the writers, I would have tried to sneak a muttered "Yeah, that's what you said last time" into one of those conversations.)

So are those who complain about plausibility. That's a bit like complaining about Jack and the Beanstalk because as far as we know there are no magic beans. Still, as the characters in Rise of Skywalker talked of "making the jump to lightspeed," I kept wondering if any of the writers knew what a light-year is and how many of them separate the stars from each other. If I understood the opening, most or all of the action of this movie is supposed to take place in sixteen hours. 

And the space combat sequences are tiresome. And so are the light-saber duels. And after eight movies in which the storm troopers' armor protects them from nothing, and they are able to hit nothing with their blasters, there's no reason to change now. And I really don't care about the race-'n'-gender tallying that popular art today is obliged to acknowledge.

All that said, I enjoyed it, I was even touched by it, and will probably see it again. Part of the reason for that is nostalgia. Here's what I said a few years ago, after seeing Rogue One (which is not one of the nine, but fills in the narrative immediately preceding Episode 4, i.e. the original movie):

Princess Leia appears briefly at the end, and the filmmakers somehow gave her the face of the young Carrie Fisher. I was oddly and surprisingly touched by that, as I had been by her recent death. In trying to figure out why, I concluded that it was partly because the original movie had seemed such a breath of fresh air to me. I remember very well the night my wife and I had gone to see some other movie--I have no idea what it was now--and saw the Star Wars preview. We looked at each other and said "We have to see that." And we did, and it was delightful.

The '70s had been a fairly dark time in some ways, a come-down from the crisis of the '60s and at the same time a sort of consolidation and solidification of some of the more negative things, and movies especially had grown considerably darker: the Dirty Harry movies, for instance, and more artsy works like Taxi Driver. And for me personally it had been a difficult period. Star Wars was a complete departure from all that, with its young and brave heroes and heroine and its simple (or simplistic) war of good and evil. It was also witty and imaginative, which may be hard to remember now that it's become such a part of our culture. It was simple fun, but it also celebrated virtue with no irony at all. 

And part of it is what is suggested by that last sentence: beneath all the often-silly trappings, there are profound truths at the heart of the whole saga: the power of love, renunciation, and sacrifice; the potent but self-destructive lure of hatred; the understanding that one must not do evil in the service of good. Those are the things that touched me in the movie, and if there are logical and narrative holes in the way these are worked out, I was not bothered by them. Maybe that's one advantage of not being a true fan.

Related: also because of the grandchildren I've watched several episodes of a Star Wars spinoff series, The Mandalorian. So far it's entertaining, but I wouldn't say much more. It was mentioned in the comments here a week or two ago, and I noted that the Mandalorian is essentially the Eastwood character from a spaghetti Western, even to the point of having Eastwood's voice. It seems I'm not the only one to notice this:
