I like it for what it is. Some of the things that could have been explained/shown better earlier are that the Aces race in their down time to keep their flying skills sharp for when raiders attack -- it's not racing just for racing's sake; and I'm in the midst of a binge re-watch and am only a little into season 2 at this point, so if I missed it first time, oops -- but I wished Our Heroes™ had found out at some point that the First Order had hired the pirates to harass the Colossus (it gets close in one episode, but is never followed up that I remember).
The characters are rather simplistic, but they do develop -- just maybe not as much as we might have liked. There's definitely a clash between the feel of the "filler" episodes and the "arc" episodes. There's some frustrating (in a real-world, no-easy-answer sense) stuff about why people supported the Empire, then, and the First Order, now. And I do like seeing how people react to the events of TFA and TLJ. And I can't help but like that the main character is a good pilot and has a good heart... but not much else. Kaz has a hard learning curve over the series and I feel the show's biggest failing is when they have him revert, for a scene, for an episode... He should never have been the same after the season one finale, so any time he acts like early-first-season Kaz after that it feels off.
Overall, "I've seen worse".
