I watched this movie years ago and completely forgot about it. Once it started, it looked so similar to something I'd watched before and alas by the end of the movie I remembered everything. Since i watched it so long ago and obviously I'd forgotten most of it, it was nice to experience the whole thing yet again. I didn't even realize my now favorite actors were in the movie. The story seems kind of simple and straight to the point but I think the back story is what truly carried it because it is one plot twist you definitely don't see coming. Throughout the movie you're just left wondering "why". The acting was so marvelous I commend Lee Min Ki especially because he portrayed his character the best in my opinion. Every role complemented each other no-one was outshining another which made it seem much more realistic. I don't remember the music honestly I was too busy trying to figure out the end game. Seeing as technically I unintentionally re-watched it, I wouldn't mind watching it again with someone. I'm a huge fan of psychological dramas and movies. Things that make you think like "damn what could I have possibly done if I were in that situation?" I definitely recommend this movie the acting is superb the story is simple but complex in its own way and it really makes you question yourself and how you would react to certain situations. But I have to say for me personally by the end of it.....................i think they deserved everything they got.
