Kingdom is a great series!
It starts off initially with weird animation for the battles, but once you get used to it, it is a fantastic series.
The same VA that did Ichigo from Bleach also voices Xin, the main character in Kingdom. His goal is to be China's Greatest General. And the series follows his rise from peasant to 100-man general. Then it's onto Kingdom S2.
