I also just finished watching season 3. The last half was really good and the way they ended it made a lot of sense, for various reasons. And it felt like they escaped from their Disney Junior cage just a bit.
Kanu, I also felt like the last episode was a bit off, but more so that it felted rushed than anything else. I was quite happy with the way things ended overall. The ending felt earned.
Anybody else besides Kanu and me who are all caught up? I want to talk spoilers. Talking in vague generalities is hard.
