If you're a fan of action, suspense, supernatural elements, drama, martial arts, or all of the above, you'll probably like this show. It takes place in an AU kind of post-apocalyptic future, where Barons (essentially slave owners in some cases) control divided up territories of land and war with each other over control. The lower classes have very little freedom and choices- most either work in the fields or become soldiers in their baron's armies, but let's just say not the typical fighting style of a soldier.
The lead, Daniel Wu, was a great choice. It's nice to see an Asian male lead, too. The actors are all talented. My favorite character besides the two mains is the Widow- you'll figure out why if you try the show. There's strong women in this show, it's far from being all male dominated. Lots of kicking a** and it's a very original take on the genre. It might seem like the post-apocalyptic thing has been overdone but this is like nothing I've ever seen in the genre before.
