An arc that had really good quality was the one with Plo Koon and the Malevolence... There was a great set up, mid-point, and ending... It included main characters, minor characters, space combat, ship combat... Had it all.
When they touch on the real war, the point of a series called Clone Wars if you ask me, then they really do well. Clones, fighters, space, landing craft, warring on worlds that don't want it sometimes...
This insurgency stuff, to me, made no sense. I still feel it was silly from top to bottom in its premise really, and then the dumbing down of the combat just killed it for me.
