I take your point. I’m a huge Star Wars fan, but I think it’s entirely reasonable (and common) for someone to be a fan of, say, the original trilogy but not the prequels, or to love everything except The Last Jedi or whatever.
But some of the new stuff is (in my opinion) actually really good! So when I hear there’s going to be new shows/films in the Star Wars universe, I won’t automatically say it’s going to be bad because I have reason to think it might be quite good.
And part of the reason it seems like Star Wars is an encyclopedia is because fantasy (and Science Fiction, which Star Wars isn’t, but has been influenced by) typically include a lot of worldbuilding, full of things like original languages, technology, lore, locations, and history. These things make the story feel richer, so many fans enjoy the films more when they learn the backstories and details.
The best part about Star Wars is how the story is enjoyable even if you don’t get into all the details.
The Mandalorian is the best Star Wars I've seen since the original trilogy.
