At first i thought its going to be a boring drama since theres no romance story, however it didn't failed to amuse me. Instead of feeling bored while watching, it made me wanted to finished the current episode I'm watching so i could go ahead with the next episode..its so intriguing, and it made me glued until the end. Congratulations to the whole staff and actors, specially namkoong min for this wonderful work..

If you want an action film,with a non stop heart pounding scenes, this is perfect for you. I love the detail of the stunts, the actors characters very well portrayed, and ofcourse the emotional impact...overall a must see movie.

Wowww seriously the comments here are so fascinating...feels like reading an entire film review of critics...but truthfully...they are all way too awesome..they describe and referred everything I thought and felt towards OSN...thank you...you just save me the space and time to discuss how beautiful this drama really is...a must see kdrama..highly recommended.

Tragic but very well done plot...ending was heart breaking...but realistic...all the characters are superbly played by the actors. A must see movie...
