I liked the bad batch arch, they're going to play a major role in what happens next.
I haven't minded the start of the current arch, its been slow and the sisters aren't great, but I think they've done a nice job of her transformation away from being a Jedi with all the rights and privileges and all of those Jedi that would have bailed her out of her mistakes. From what I've heard, the last episodes of the series are pretty dynamite.
I have some theories as well.
