It's ok, not great. It's so close to being so much better too; there are lots of parts that work well, and some that don't, at all.
On the positive side the acting is mostly ok, casting is mostly good, and the story is fine. The look and feel is good. Some people critique swordfights for not being choreographed better but that's for people into LARPing to debate; it's ok. Those characters are good, already developed from Star Wars Rebels, or it seems fine if you didn't see that.
Then some of the finer points are so bad. The Ahsoka character portrayal makes her smug and condescending, even sometimes when she's alone, she can still look smug and disapproving. Of what?! I don't know if that's Rosario Dawson's take on the character or direction she is working with. She talks really slowly to add dramatic effect, or just looks around. The Hera character is nothing like the cartoon version, who was more commanding, creative, active, and sensitive. It's strange that a cartoon character would have more depth. The rest isn't as bad.
It always was going to be a stretch to make the Sabine character a Jedi, based on the earlier story line where she wasn't, and they botch that, not filling in details at all. After however many months or years of training under Ahsoka, and a fallout, upon reunion she first tries the training practice Obiwan had Luke do essentially as the first step in his training, sword / lightsaber training while blinded. Sabine explains that she can't feel the Force or move things, to her Jedi--sort of a Jedi--trainer / master, who she had learned under for at least some months. It's dumb.
For sure they'll keep showing parts that work and parts that don't, and a show that could've redeemed the franchise, as Andor did, will instead seem great to some and like more of the same decline to others. The Obiwan series was like that; adjust a few things, especially story line components, and it would've been good, but it wasn't good.
