The show has been so boring due to the subpar writing, acting & directing. None of the characters appear to have any inner life. They seem like characters in a video game just waiting for the prompt to say their lines. Chatbots have more depth.
& once again we have another series where heroes & villains make one stupid decision after another in order to get from one lazy plot point to another. There is no dramatic tension & the stakes don’t feel real.
Thrawn doesn’t feel like a threat to the galaxy because he comes across as an idiot. He has always been, to an extent, a stupid person’s idea of a genius - his ability to outwit an enemy based on psychological flaws revealed by a species’ cultural artefacts was laughably ridiculous - but at least Zahn tried to make him seem efficient & ruthless. In Ahsoka he just comes across as a cartoonish incompetent buffoon.
Filoni has shrunk the galaxy - & even his new galaxy seems to amount to nothing more than a barren & misty moor in northern England.
The art psychoanalysis is ridiculous, but at least it’s different enough to be interesting.
I think the reason Thrawn still feels like such a towering threat is because there’s been no competent villain in any Star Wars movie past the OT. The bar is so low here that even a halfway decent Imperial commander would feel like a terrifying mastermind.
