I wouldn't be so harsh as to use the words "clown franchise" but Ahsoka absolutely pandered to the niche franchise. Again, I wouldn't mind if Ahsoka introduced Rebels characters organically rather than shoving them in episodes without proper introduction. I would argue that S2 of the Mandalorian did a better job of easing in other established characters like Bo-Katan, Boba, Ahsoka and even Luke, weaving Din and Grogu's journeys with them in a logical and natural way, keeping both casual and obsessive SW fans entertained and excited. Ahsoka, for me, felt emotionally flat and the overall story (find Ezra, find Thrawn) stagnant by not introducing these characters properly - they were all tell, don't show. I would take an idiot's guide 101 to these characters if it will flesh them out and make me see the whys hows and whats. Why is Ezra so important to Sabine, why is Thrawn such a threat? How do these red witches and their magic work with the Force around them? I could go on, but I am tired now. Give us casual fans the basics please.
Now I think I get where The Mandalorian is going in S4 or at least the film(s) that Filoni is/are planning. Thrawn is the big threat and Ahsoka, Din and company will be there to fight him off. Which is all fine and dandy, but I fear the overall arch will drown out what brought me back to SW in the first place. You didn't need to know any SW lore, you didn't need to have consumed all the SW media over the decades and you didn't need to be a walking SW encyclopedia. All you needed was an open heart and a childlike wonder as you watched a small, yet beautiful story of a stoic bounty hunter, finding inner peace not only with his faith and culture, but in being a father to a magical child in a crazy galaxy far far away.
