Recap: The Chaser Episode 1

I've heard only GREAT comments about The Chaser but surprisingly it was not recapped anywhere. I suppose at the end of the day, there was just not enough pretty (faces) to attract the interest of the audience (outside of Korea anyway - it did very well with the Korean audience). The funny thing is, I never had the urge to check it out until I saw Haha bumping into Son Hyun-joo on Running Man. And then, Kim Sang-jung and Jang Shin-young became the guests for one of the episodes. And even though they played loosen-up versions of their characters, I find both of them indescribably magnetic and arresting. So here I am hopping on the bandwagon trying to find out what is it about The Chaser that made it such a big success.
