A complex tale of friendship, love, betrayal, revenge, corruption, and patriotism in a historical period of strife for South Korea. Excellent cast and acting. I feel the story could have been told in a few less episodes though. Great fight scenes using actual martial arts techniques. Warning: very bloody, lots of ultraviolence in addition to the usual buttkickery. View with caution with younger viewers. Most likely this drama was way over budget on the line item for stage blood.
