I had to work myself up to watch this one. I knew, from the plot summary and other sources, that this wasn't going to be a feel good happy smiley romantic comedy, and I'm glad I steeled myself against it before I even started to watch, because I don't think I would have got through it otherwise. On the other hand, because of this, my emotions were less engaged, and so I think it was hard for me to connect with the characters here. Overall, I think the writer, actors and director did a good job of bringing this story to the screen. They treated the heavy subject matter with respect and honestly, which truly, is the only way you can treat it, and that's not to say there wasn't any levity in the show, because in life, no matter what you're going through, there will always be those moments of levity or brightness. But for me, it was just too heart wrenching and a little bit close to home. I don't deal well with that type of drama, because generally I watch to escape reality, not to be immersed into it. Lee Dong Wook was hot, if a little stiff - I kept being reminded of his role in Goblin which I had watched first and where I thought he was just delightful. The tango scenes were hot. There should have been much more tango and less... dying. Kim Sun Ah was fantastic in her role, and the character really did come into her own. As for the ending... honestly, I was expecting it to be a lot more depressing than it was, so I was satisfied with what they did with it.
