Although Obi Wan was pretty meh, I think that most of the recent stories set during the Rise of the Empire are the best because the heros are the underdogs and the Empire is such a formidable foe. I think a lot was missed by not exploring the The First Order's rise, and just that we were introduced to them as the new badies who are just like the empire. I guess Disney is relying on Filoni to fix that after the damage has been done.
