For those of you who dug Wu Dang, this is one of my other favorite martial arts/kung fu epics of the past few years (it just popped up on NF this week). It's completely over-the-top, slightly in the vein of Kung Fu Hustle, but with a "historic" back-drop, so it kind of owes a debt to Once Upon A Time In China, as well as King of Beggars (two classics any self-respecting fan of the genre should see, imho). Oh yeah, there's nods to Scott Pilgrim, too...
