This is not a good movie. It's like they filmed a 3 hour film, but had to cut half of it out. I was constantly thinking I'd missed scenes (although considering I watched it online, there is always the possibility that the copy I watched wasn't complete). There was hardly any character development. I didn't care about her relationship with her ex-crush because we never really saw her actually caring about him. She said she did, but there was nothing else to really suggest it. Jang Geun Suk is a great dancer, so those scenes were good to watch, but did nothing for the plot. I gave the story, cast, and music decent scores, because they were fine. It was the directing, editing, and overall film that I had a problem with. Very disappointing.
