I've never been happier while giving a perfect 10 in every field to a show or a movie. This movie is heartbreakingly beautiful. I'm still embarrassingly wiping my tears as I come to terms with the fact that the movie is really over. Reading the synopsis, it felt like a slightly above average interesting adaptation of the same old love triangle. I wish I could travel back in time to two hours ago and smack my younger-self for thinking such a thing about this movie. I've never seen a more breathtaking execution of a veteran plot. The characters of the story were hauntingly realistic and believable. Love makes you do things you wouldn't normally do, we see the characters go through that very naturally. When you watch this movie, you'll find yourself understanding the mind of an assassin who loves an innocent girl; you'll find yourself aching for the girl who's lost her voice and the man she loves; you'll find yourself wanting to believe there's got to be some good in the world. The story makes a warm spot in your heart and you find yourself so engrossed in it that you forget you're just a spectator. This is the sort of magic that made me love Korean cinema in the first place. I cannot even begin to describe how awed I am by the performances in this movie. I've only seen Jung Woo Sung in A Moment To Remember before and I'd thought he was amazing, after watching this movie, I take it back. He not just amazing, he's absolutely brilliant. Jeon Ji Hyun doesn't cease to impress me. This is the 3rd work I've seen of hers and all have been great. Every body on the cast did such a spectacular job, definitely worth commending. What do I say about the music of the film - it's stunning. The incorporation of Classical music into the movie was a touch of perfection to the masterpiece. I enjoy listening to Classical (I'm not into the technical aspect just the vibe and effect that the music has on me) and it was really nice to see the music being used so amazingly. It felt like the soul of the movie, when there weren't dialogues to convey the emotions, the music did the work. Perfect harmony. If my ratings and the praises above aren't enough of an evident as to how much I loved this movie, then I don't know how else I should convince you to stop thinking and just watch the movie already. I am 100% sure that the moment you see the beautiful scenery and hear the lovely song playing in the background in the first few seconds of the film, you'll be hooked in and that hook is going to be painful to take out by the time the credits start to roll. HIGHLY RECOMMENDED. Don't hesitate one bit.
