Dunno why it took me so long to get around to watching S3 considering how much I enjoyed S1-2. Show remains excellent, although I really didn't like the Saw cameo, and not because I didn't like Rogue One, but because the more prominent the cast of Rebels gets, the more ridiculous it gets for them to have never shown up in the events of the movies. Which means they'll either have to kill them all off (unlikely), come up with some contrived reason as to why they happened to be busy on another assignment for the three most important battles of the rebellion, or just leave it hanging when they end the series.
Also maybe I'm in the minority here, but I really would have preferred the Ezra's temptation to the dark side to be a subplot for a couple episodes, rather than being introduced and resolved all in the season premier. Don't have to keep it as an ongoing plot for the entire season, but wrapping it up in the first episode completely undercuts the significance of him using it and how dangerous holocrons are supposed to be in the first place.
