The more Star Wars content I engage with the more flabbergasted I am with people complaining about how politics shouldn't be in it. Thrawn's storyline is very obviously surrounded by racism, xenophobia, and overall governmental corruption in favor of those sticking to the status quo. Star Wars will always be political.
Being able to see the works of Thrawn's perception and strategizing is amazing, but Eli being there as a reference for how unusual from the universe he is is definitely the high point of the narrative. Pryce's part was really...eh. She's not meant to be likeable but I also couldn't care about what was happening on her side of the story.
The story takes a little while to pick up the pace but my main complaint is that they really tried to hammer the point that Thrawn was "politically analphabet" when really he was just really blunt and found the bureaucracies ineffective. Can't say I disagree.
