Ahsoka really only has two broad problems. First, the pacing of the first three episodes needs to be tightened up considerably. I swear so many user reviews I’ve read say the long pauses and slow, monotonous dialogue put them right to sleep. Second, like all Disney SW content, too much of the plot seems overly contrived. Sometimes that can be mitigated, sometimes it can’t.
On another note, Episode 4 was surprisingly strong and well-paced. There’s very little I’d change there.
