The ending was meh... At least it tied some knots together. I'm feeling evil, if Yu Wen Yong can't be happy why should Lan Ling Wang, with that said at least he didn't die and had a son. Like adjani said, Xue Wu did paid a huge price for peace but I don't think the ending was necessary seeing how the Zhou army was outside of the city already, Zheng Er and Gao Wei would have been killed regardless. Though I guess this further illustrates that peace is not an easy achievement and it requires many sacrifices to obtain.
Two cry-worthy scenes. First being Gao Wei & Zheng Er's deaths, as panda-pop said, I wish they showed more back story on why Gao Wei was willing to go to such lengths for her. I think his story would have been cute. Second one was when Yu Wen Yong told his warriors/subjects to face the other way and not utter a word, and he broke down. The flashbacks were mighty fine to evoke his history of love with Xue Wu. It really did show how much of an impact she made on his life to be able to break down 'infront' or more like 'behind(?)' his subjects. Definitely not a Yu Wen Yong characteristic, but it shows that he is indeed made of flesh and blood.
I think I quite like the ending. I didn't see how else they would have ended it. Any thoughts on alternate endings?
