Has anyone else experienced this?
I'm rather the reverse. I'm always more critical of movies the more that I watch them. I can't think of a movie which I didn't like, but which I had a better opinion of on rewatching. On the other hand, I can think of many movies I remember liking, but which didn't survive a rewatch.
I slept overnight on the concrete to get tickets to TPM, not because I needed to by that time, but just to be there with my fellow geeks who had loved this movie since they were tiny. And the first time I saw TPM, I thought it was OK. It was a beautiful film, and I was mostly bothered by the lack of memorable lines other than the overt insert of familiar ones. It was only on rewatching it the next day that I really started finding flaws that I found serious and which started to detract from my enjoyment.
TFA I enjoyed for the first 30 minutes or so, but then about halfway through the movie I observed I was actually bored. And the more the movie advanced, the more I was annoyed with the portrayal of Han and Leia, and the more I was annoyed how it seemed to have almost exactly the same structure and plot points as 'A New Hope', and the more I was annoyed by the illogical actions the characters were taking purely to hit the writer's desired plot points. By the end of the movie, I was actively hating the movie, and in particular I realized that all the mystery boxes that Abrams was presenting to the viewer actually didn't hold anything. I didn't know who the 'Knights of Ren' were because Abrams didn't know either. I didn't know who Rey was because Abrams didn't know either. I didn't know why Luke's academy had failed because Abrams didn't know either. I didn't know why Luke was in hiding because Abrams didn't know either. I didn't know who Snope was because Abrams didn't know either. All these supposed mysteries that Abrams was telegraphing as important to the story where just gift wrapped boxes with no gift. It was plain bad writing that didn't bode well for the future.
TLJ not only confirmed those fears, but it was just horribly written to the degree of being unprofessional. My tolerance of the movie ended within seconds with the lame straight from an after school TV show dialogue between Hux and Po which rivaled or exceeded in inanity any of the dialogue from the Star Wars TV specials, including the Holiday special.
I think I could partially forgive all the stupidity of the writing and the vapidness of the plot if Han, Leia, and Luke were given better less cynical treatments, or even if the story had been about those three failing and their failures had been something believable and foreseeable in hindsight based on their character. But Leia seems to fail only because she is a girl - which is insulting and infuriating - and Han and Luke fail in ways that are contrary to the central aspects of their character that we have seen up to that point.
There are a few things I like about the two new movies. Mark Hamill gives an incredible performance despite the poor material he's given to perform. Although the script does nothing with her character, Rey is introduced very skillfully. Both movies are for the most part beautiful films, and both directors better handle a camera than Lucas did in the prequels. Many of the locations such as Luke's island retreat are brilliantly chosen. There are occasional moments that could have been part of a better film. Luke should be challenging the goodness of the Jedi and should be demanding a change in direction, and that was something I wanted to see, but then Luke has nothing to say and is deceived again by the Jedi in a complete jerk move by Yoda that makes me dislike him now even more than Obi Wan. And the temptation by Kylo of Rey is a well done scene, albiet one which in context makes absolutely no sense given that only hours have taken place since Rey watched Kylo brutally murder his own father, a man she had a developing friendship with.
But overall, these are just bad movies, and you aren't missing anything by missing them.
Of the new ones I have only bothered to watch Rogue One and I was not impressed. Perhaps in a few years if I watch it (and the others), I will appreciate it more.
Rogue One had two flaws. The first is the pacing of the first half of the movie, which is disjointed and slow. There are too many cuts between locations, and not enough going on that is meaningful. This is a minor flaw. The more serious flaw is that there is some serious illogical hoop jumping that characters are made to jump through in the middle of the movie in order to achieve certain plot points, and it's both bad and unnecessarily bad writing. In particular, I'm thinking of Rebel commands decision to continue to try to assassinate the lead engineer on the Death Star project AFTER they have learned that the Death Star is already operational, something which makes absolutely no sense at all and which could easily have been corrected. Beyond that, how much you like the story tends to be a matter of opinion. Those that like it are able to forgive the flaws given the big pay offs in the final act of the movie, and like the dark gritty tone that the movie sets and the questions that it asks about war and how clean it can really be no matter how just your cause. Those that don't like it tend to not like the dark, gritty tone, and conflict with moral ambiguity in the middle of what they have always considered escapist fantasy.
