Lee Byung-hun stars in one of my favourite movies "A bittersweet life" so I am always going to be generous with my rating in whatever he is in. As usual he puts in a great performance along with the whole cast and there are some really great action scenes which reflect the budget. My issue is the story does not flow as well as it should and the series concentrates on the big explosive scenes and not enough time on the development of the characters. Enjoyable action packed drama but could have been great.
