The lightsaber choreography was awesome. Otherwise I felt like the show was pretty meh. I feel like they were trying to show that Jedi and Sith aren’t just good and bad, and rather that they’re complicated and nuanced, but at the end I didn’t feel like that message landed at all, especially with the cameos you mentioned but even without them. The black and white costuming was really heavy handed, too.
Yes, I think you nailed it. After a whole lot of fairly un-nuanced character development for Osha and May, it was like they just switched brains in the last episode. What the heck? And there was definitely no payoff to any of the one/two stuff.
