I know people are going to rate this review as 'unhelpful' purely cos i didnt like it as much as I thought it would and the MCW and SJK fans are gonna shoot me! but drama wise it did nothing for me! I had thought that this drama would become one of my favourites but unfortunately it did nothing for me. I had mainly wanted to watch this for Joong Ki, Chae Won an Kwang Soo, and indeed their acting and purpose of the drama I was satisfied with but there were many a places and the plotline of the drama in general that I wasn't satisfied with, but it had SOOO much potential!! This is one of the worst melodramas I have watched because it feels like everything that happened didnt really have a purpose or if it did then it wasnt carried out very well, for certain story lines we got the build up and a terrible climax or we didnt get a build up and things just happened and we were some how expected to just understand where the character was coming from, but I couldnt. Joong Ki and Chae Won's acting skills were great, how they were about to carry their emotions across so well, Kwang soo too, even though he didn't appear in a large proportion of scenes but each time he did his character was the one who gave the words of wisdom and helped the characters hold themselves together, so he was important in that sense, without him I dont think the drama would have worked. The main problem I found was the plotline, to be everything was so brief, we only grazed over the past of everyone without enough depth and not allowing enough time for it to sink in and let me feel for the character properly before something else happened (it would have been much better if the events actually had a purpose too, and not just dramatic events lined up together). I was so bored of this drama until the major plot line change near half way through the series, all the previous episodes just didnt suck me in, I wasnt interested in the revenge because there wasnt much 'revenge' to go off from. Most of it was predictable and for the first 8 episodes I was literally watching just for the mysteries behind the main leads characters and Kwang Soo. Then the plot twisted halfway through with new obstacles to face, but it was as if the obstacles before that didn't seem to matter as much before and even to the end there were still problems that were overlooked after having such a dramatic build up or sudden event that happened; as if they were rushing to finish it... This drama didnt make me cry, it didnt make me shiver or tingle in response to the storyline, I probably had the most fun watching Kwang Soo act more so that the other supporting roles! The OST was average, I didnt hear it most of the time to be honest, it was always kinda in the background so i knew it was there but it didnt captivate me to want to listen to the songs more. Now that ive watched it just to see what would happen in the end, i'm still a bit confused at the ending, and I most likely won't even consider rewatching this. (The rewatch value ive put is literally just for the 2 main leads and Kwang soo). I'm glad that for, what seems like the rest of the population that it was received so well for the main leads, that they gained more recognition for it and their acting skills but I was just rather disappointed with the story.
