That does not surprise me. The sequel trilogy was an opportunity to tell a new generations story, and they completely failed to do anything significant with it.
What does surprise me is that so many people were watching the series, Mandalorian and Andor. About half the audience if his graphs are right.
Andor was a very well-written series addressing some serious (and timely) themes that just happened to be set in the SW universe. That give at a chance at broader appeal, and the almost complete lack of the mythology, and relatively little tech also helped it to be more approachable and relatable to the uninitiated.
Andor's story in the series, and the film, is easily one of my favorite, if not the favorite part of SW for me, especially given the current state of the franchise.
I didn't like last 3 movies at all. They killed the vibe and universe. It was weird that they built a plot around the fact that "rebel hero Luke Skywalker" randomly becomes mad old guy and tries to kill his own nephew because "he sensed evil in him", eventually giving Kylo Ren serious psychological trauma and driving him to the dark side (and who is Luke now, a traitor, a mentally unstable old man or Grey Jedi? No wonder he decided to go exile). While it has some deep philosophy to think about ("bad isn't inherently bad" or "white is not always white, and black is not always black"), but whole implementation is wrong: Luke was key protagonist in original trilogy, which had the main fan base, and Disney just goes and says "Ok, time for something new".
"Ahsoka" was something different tho, not as boring and doesn't revolve around Skywalker family drama at all
Luke ending up as an angry hermit, and Han Solo, of all people, effectively meeting his end by being shivved by his and Leia's emo son? I would have loved to be a fly on the wall in the meeting when that pitch was made.
It might have seemed like a good idea to some people at time, but to me, that is probably the biggest crime, so to speak, of the sequel trilogy, having those characters meet fates I'd neither imagined, nor ever hoped that they would.
Even if the Skywalker tree had to serve as the bridge to the new generation, it could have been done differently.
I can't, or don't remember what effect Carrie Fisher's death had on the story, but I'd like to think those characters deserved better than that, regardless.
If a SW film is rerun on TV, I'll leave it on, even as background noise. Except for the last trilogy.
From the standpoint of only having watched the films and TV, Ahsoka was ok.
