This video does a great job at pinpointing exactly what I hated about the sequels: https://youtu.be/CuuDTnMPMgc
In one word, bathos. To many jokes, too many quips, it all made light of the serious undertone. Andor and Rogue One were great because they wanted us to feel the drama, the huge weight being lifted. They didn't belittle the audience with a short joke because they didn't think we could handle the drama, they laid it out solid for us.
It's why I get goosebumps when I think of the guy yelling "LAUNCH" screamed with terror in his voice, or misty eyed thinking "I am one with the force the force is with me", or actually anger thinking "One way out". Those were moments, true cinematic moments where the director let us feel those. They didn't have a joke to lighten it. They didn't poke fun that we're watching Star Wars. They let us feel it.
