I think the show is good, but I also completely understand a lot of the criticism I see, and even agree with it to some extent.
First and foremost- this show should have been animated. It is a sequel series to an animated series, Star Wars: Rebels, which is itself a companion series to another animated series: Star Wars: The Clone Wars. Dave Filoni is clearly at his best when it comes to animation. Had this show been animated as well, it would help with some of the other issues, such as the stiff acting at times, and the lightsaber chorography (which I actually don't think is bad in this series). It also would have allowed the Clone Wars and Rebels voice actors reprise their roles, which would have felt less jarring, to me at least.
My Real score for this series is like a 7.5 out of ten, but I also may be biased due to my love for Clone Wars and Rebels
