Stranger

First of all, I loved the background music - its gripping. It a very well written and executed how, with good story line and acting. You wont know anything until the very end, and keep doubting every character.

Its a decently paced show, and you wont find one boring moment - amidst all revelations, blame games and well, causalities! Also gives you a sneakk peak into the power game in South Korea.

Give it a try if you like suspense thrillers. You wont be disappointed!
