Jang Hyuk is a brilliant actor and one of my favorites. The rest of the cast was also good, writing was until last episodes, and the series worked well for me until the last few episodes when there was so much violence it felt way over the top. Then there were repeated scenes like they were running out of steam. And, seriously, a cop who holds a gun on a really bad guy repeatedly yet never pulls the trigger. At any rate, mostly a good series with the too-frequent series issues of not being able to remain great until the end.
