I had been anticipating this drama for well over a year (before viikii became viki.com and almost impossible to watch a lot of shows), and I had hoped and prayed that I wouldn't be disappointed, and I wasn't. To compare this to other "musical" drama's is insane, because unlike most of those drama's this one actually does follow the theme of "musical". The story, is as it says it is in most story summaries you read.. but what those summaries fail to mention is that it is spectacularly written, its also about human relationships. And the story had, not necessarily side stories/plots, but background and reasoning, that made you go "Oh so that's why" in a few places, loved that.. Each of the "main" characters, are well thought out, including development. The acting is stellar. Straight up, even the character's you don't like, are so well thought out, that you can't be mad at the writers for making them that way. Every character in this drama has his or her place, take one away, and the drama wouldn't be the same. I was really impressed by the acting. I know most people, would start to watch this for Daesung, but don't. That's all I can say, do NOT start watching this for Daesung, I did, and not that I was disappointed with his acting, I wasn't, I just didn't like his character. Music, well it is about musicals, so of course the music has to be good, and not only was it good, I was very impressed by how good it was in places. I will re-watch at some point or other... The reason I didn't give this a perfect 10, but a 9 instead was because, all the way up until the ending the writing and so forth or stellar, but the last episode was just so sub-par to me that I couldn't bring myself to give it a perfect 10.
