Show started off bad, got pretty good in the middle, and then kinda fell off again the last 2 episodes. Some of the biggest continued problems with these Disney Star Wars shows are large logic gaps in the storytelling, underdeveloped characterization, and setting up for future seasons/other shows which leaves you with an overall feeling of incompleteness. Ahsoka felt like a blank slate and the least compelling character in her own show, and that's saying something with Sabine who looked and acted like an annoying angsty teenager the whole time. And yeah, you definitely felt the complete absence of the two most best characters in this finale which were the two dark Jedis/Siths/whatever.
The grunting Zombie Troopers were really funny, but at this point I don't know how anyone can still get mad about that kind of stuff in Star Wars. After 2 very underwhelming movie trilogies and roughly a 50% batting average on these shows, if you're someone who is still very much into the Star Wars lore, mythos, continuity, etc. then you're a trooper. But to me its basically Terminator at this point, I no longer care whatsoever and just hope for an entertaining time.
