Overall, I'm very happy with the Marvel Cinematic Universe, right up to just before Endgame. Endgame felt like a victory lap. The fight was awesome, but Disney sappiness seeped into the lead-in. After that, I have no idea what criteria they used to assign movies and serieses, but script quality wasn't on the list. I'm grateful for what they gave, but it's all over except the milking.
Star Wars was basically doomed the moment Jar-jar walked onto the stage. The original series was undoubtably epic but, as hard as that might have been to do, Lucas overplayed his hand. He also lost touch. He drew the interest of a younger crowd, but I won't try to mansplain their perspective.
Overall, I can't say that Disney did any worse than Lucas himself would have. Episode VII was insultingly derivative, almost as if they were trying to figure out why the original was a success. The later two felt like word salad, and they ripped some serious chunks out of the continuity along the way. On the other hand, Rogue One and Solo were solid. What I saw of the Clone Wars animated series was fun, and I enjoyed the Bad Batch. Baby Yoda drove me away from The Mandalorian before I could form a solid opinion.
A few decades ago, I could rely upon Disney to crap up anything they touched. Now I think they're too big, and they can't spread the crap thinly enough to cover the full surface of their empire.
