The veteran actor, Lee Sun Kyun, delivered a powerful performance that anchored the show, as expected. It's really heartbreaking to lose such a big talent. Rest in piece. The drama didn't exactly break new ground with its plot or characters, but it managed to hold one's attention through its well paced narrative, occasional power shifts and a few unexpected twists thrown in. The cast does their thing, but some of the characters feel a bit like cardboard cutouts, lacking some life in them. While the drama dipped into melodrama sometimes but it struck a balance between suspense and storytelling. Overall, it's a pretty decent drama around corruption and power struggles.
