First of all, I haven't watched the drama version so it's easy for me not to compare. Since it's based on true story, I don't see any need for me to give anything less than a 10. It's beautiful, saddening and realistic. The casts were great. They acted true to their characters. A caring family, a professional doctor and a girl who's not afraid to act as a handicapped person. I didn't pay much attention to the songs but I would say they're good and I didn't hear anything out of place or not fitting to the situation. A beautiful story overall that I wouldn't mind re-watching. I will probably watch the drama version too and see what it's like.
