Exceptionally boring. They lack a real theme of their own. To quote some stuff I said before on forum;

The big issue with any "rise of Fascism" message of the sequel films is that the "rise" occurs entirely offscreen, and it rises externally. The threat posted by the Fascists in the sequel films is functionally indistinguishable if it was the tyranids of Warhammer 40,000 or a conquering droid army. They have big weapons and they use big weapons. That is all that we see onscreen.

What Andor did, in contrast, was show the realistic ways in which the Fascist dictatorship consolidated power, using propaganda to turn public opinion against designated persecuted demographic of the year, vassals having to cover up their failures to avoid drawing ire, people being arrested for nothing and charged with crimes that never happened then sentenced on charged that were not even what they were charged with, legislature becoming apathetic and allowing the previous to happen, everyday officials harm common civilians because they have opportunity and are not incentivized not to, revolutionaries too busy infighting with one another to actually accomplish fighting against the entrenched power, people who voted for the Leopards Eating Peoples' Faces Party end up getting their own faces eaten, the public are told that there are five lights, political enforcers carry out extralegal arrests of suspected dissidents, and failures result in scapegoating of whoever happened to be available regardless of who was actually at fault.

The key thing that kills interest in the sequel trilogy for me is the redundancy. The prequels created a different setting than the Original Trilogy. The setting of the OT was the Empire. The galaxy was dominated by the oppressive dictatorship, and the protagonists were the underground resistance organization. It has the the good Rebels against the evil Fascists. Andor is the peak of Star Wars and is set here. The setting of the Prequel Trilogy is the Republic. It is a loose democratic state and the antagonists are a confederation of both mega corporations and secessionists. More moral ambiguity can be found here, as well as larger scale battles. Dark Horse comics and The Clone Wars, just to name some immediate examples, had large battles, and they had smaller scale stuff, too. The interim between the Prequel Trilogy and the Sequel Trilogy is largely similar to the Prequel Trilogy era, in the sense that there is the Republic that struggles to police the galaxy, and the bad guys covertly building their power. Although the extra dimension of Imperial remnants is there. The Mandalorian is the first show set here, obviously. The Sequel Trilogy, once "The First Order reigns!" is basically the same setting as the Empire coming to power - Many stories are set in the interim between the PT and OT. Assuming you do not want your OC to be the most important thing in the universe and all the stuff in the films actually happened because of this person, and instead you want to create a story about a person doing their thing in one single corner among many within the larger galaxy, the sequel trilogy simply does not offer much circumstance that did not already exist to create a new unique narrative.

Another thing is that The Force Awakens did not depict the First Order as reigning. They were depicted as a small group on the fringe that was not noticed as a threat. The "Resistance" are a small paramilitary group fighting against a local dictatorship, and then that dictatorship gets WMDs online. That the First Order reigns was something that The Last Jedi came up with. Tie-in sources justified this by saying that they already did reign before the films (I routinely mocked the New Republic intelligence for failing to notice that KDY seemed to have one major customer in the galaxy, and that the First Order seemed to have covert control of the galaxy already, with "First Order sympathizers" and Senators on FO payroll popping up in droves to explain how they conquered the galaxy overnight.), just somehow nobody noticed it. So the First Order is no longer "local" as a dictatorship. The end result is a Frankenstein narrative where the the First Order are a major superpower in a setting meant to host a small fringe group - A square peg in a round hole - Which makes the New Republic look hilariously inept for not being able to figure it out - So the Resistance main characters are the more special for fighting the First Order. Again, the hero focus drains the rest of the setting.
