I disagree. The Onderon arc was good and the Youngling arc was phenomenal, mainly due to Hondo Ohnaka. The Droid arc was unnecessary though...
As for the recent episode, I'd say this was even better than the last one. The animation and action were great as always, but the music is what really got my adrenaline going, especially in the final duel at the end. Kiner's music as definitely improved. The dialogue and voice-acting were overall, pretty good, but the scenes were rushed. I think the pacing of the entire Maul arc has been too fast and that would be its main problem. But its a problem that is overshadowed constantly.
