I will respond to both at once.
I am not a Star Wars fanboy by any means. I like the SWU, I don't love it.
I like New Hope and Empire Strikes Back. Return of the Jedi has issues. Those movies were made in a different time. I watched the Graduate a week ago. I get why that is considered a good movie, but it is also hopelessly dated and does not age well at all. New Hope is approaching 50 years. It still holds up, but I am not sure how much of the love for that movie is just nostalgia.
The Prequels had potential, but I have two issues:
1) They feel a lot like Lord of the Rings in space
2) George Lucas is a terrible Director. He killed Hayden Christensen's career and could have taken out Natalie Portman's too if she wasn't already a big star.
Force Awakens was fun, The Last Jedi was excellent, and the Rise of Skywalker is what happens when a studio lets internet fans write a screenplay.
The Mandalorian is well served by a slower pace and more character development of TV. The fact that the same frachise is alive this many years later is a credit to the source material, but its variance from the old "look and feel" of the movies is a natural modernization of franchise, and one that needed to happen.
