As a huge fan of Ji Chang-wook's acting, I must say this is one of his best roles. The story is amazing, the chemistry between the leads is off the charts and the action is jam-packed. If you enjoy action films, like the Bourne series, or Chang-wook's other series K2 - this is a great show.

I was blown away by the soundtrack and still listen to it years after I watched it - it's that good. If you love the action hero turned lover trope, this is for you!

I know some folks have likely criticized the plot length or some of the acting, but I feel that the storyline is very coherent and engaging for any action fan. I really appreciated the detailed stunts done and how the drama constantly has you on the edge of your seat.
